Padre binaries and command line usage


This page lists all the Padre binaries and their corresponding usage messages.

1. FineTune

Purpose: Tuning padre-sw ranking parameters based on a C-TEST file.

Usage: FineTune <collection>[.<profile>] ... [-perl_bin=path_to_perl_bin] [-help] [-verbose[=<level>]] [-timeout=<hours>] [-query_limit=<num_queries>] [-alpha=<f>] [-rvalues=<i>] [-adjust=<i>] [-sample=on|<number>][<mode> ...] [-conf] [-qp=padre_subpath] [-index_dir.<collection>=<index directory>] [-lock_file=<file to lock>]
   e.g. FineTune lse -daat -annieonly
   e.g. FineTune -timeout=7.5
        Use -daat0 to tune term-at-a-time.

        Timeouts and query limits:  Apply separately to each mode. Defaults
         are 5 hours and 1 million queries. After a timeout, or when the
         query limit has been exceeded, the best tuning found so far for
         that mode will be recorded in the .best file for the mode.

        -perl_bin=/path/to/perl used to set the path to perl binary to use

        -alpha sets the balance between success rate and wmum1 in tuning. [Dflt 0.75]
          Value must lie between 0 (ignore success rate) and 1 (ignore wmum1)

        -rvalues - sets no. of values to explore for optype=2 (real) [Dflt 11]

        -adjust - sets no. of steps to remove when adjusting exploration range
                   for optype=2 (real) dimensions. [Dflt 5]

        -conf extracts the mode to tune from collection.cfg. (N/A for multituning.)

        -help gives more detailed instructions and exits.

        -index_dir can be used to set the index directory for a particular collection.
         The directory must contain a index prefixed by 'index'.)

        -lock_file can be used to lock a file for the entire duration of tuning, if
          the lock can not be acquired tuning will not start.)

        -redirect_stdout can be used to redirect stdout to a given file.

        -redirect_stderr can be used to redirect stderr to a given file.

        -write_finish_time_to writes the tuning finish time in ISO-8601 to the given

2. QiTune

Purpose: Tuning padre-sw query-independent ranking parameters based on a C-TEST file.

Usage: QiTune stem C-TESTfile

Given a PADRE index and a file of useful URLs (extracted from the
C-TEST file) compute a set of query-independent cool settings
suitable for passing to padre-do which (hopefully) optimise the
difference in ave scores between the useful docs and the general collection.

3. SpellTune

Purpose: Tuning PADRE spelling suggestion system based on a test file e.g. mycoll.spelltest.

Usage: SpellTune <collection>[.<profile>] ... [-tune_bsi] [-help] [-verbose[=<level>]] [-timeout=<hours>] [-query_limit=<num_queries>] [-rvalues=<i>] [-adjust=<i>] [-sample=on|<number>][-qp=padre_subpath]
   e.g. SpellTune lse -annieonly
   e.g. SpellTune -timeout=7.5
        (Timeouts and query limit defaults are 5 hours
         and 1 million queries. After a timeout, or when the
         query limit has been exceeded, the best tuning found so far
         will be recorded in the .bestspell file for the mode.)
        (-tune_bsi - tunes the build_spelling_index params.  Slow.)
        (-rvalues - sets no. of values to explore for optype=2 (real)) [Dflt 11]
        (-adjust - sets no. of steps to remove when adjusting exploration range
                   for optype=2 (real) dimensions.) [Dflt 5]
        (-help gives detailed instructions.)

Invalid usage.

4. annie-a

Annie version 1.13 (11 Mar 2010)
Purpose: Builds an annotation index for a collection, specified by <stem>, from a list of files in anchors.gz format.

Usage: annie-a <stem> [<stem_or_file> ...] [-phrasefile=<filename>] [-deb] [-hashbits <10..30>] [-maxlines <n>] [-wts <wt0> <wt1> <wt2> <wt3> <wt4>] [-stripstops] [-STOP=<filename>] [-canon] [-rejecturls] [-rejectnumeric] [-quicken] [-maxwds <i>] [-maxlen <i>] [-build_annou=on/off] [-build_lcache=on/off] [-nep_limit=0|1|2|3]
    <stem> must reference either a meta collection or a primary index.
    <stem_or_file> may be either a stem as above or the name of a file in anchors.gz format.
 In the case <stem> or <stem_or_file> is a meta collection, annie-a will look for the anchors.gz files from each of the component collections and use them for creating the annotation index for the collection specified by <stem>. If any anchors.gz file changes for a component collection, annie-a will need to be run again for the meta collection.

-quicken    improves query performance by using <coll id, doc id> pairs. The coll id is dependent on the sdinfo file, if the sdinfo file is changed annie-a will need to be run again for the meta collection with this option. It is recommended that the most recent collection is placed at the top of the sdinfo file.

5. annie-quicken

Purpose: Convert URL references in an annotation index into (component, docno) to speed query processing.

Usage: annie-quicken anno_stem index_stem

6. build_autoc

Purpose: Builds an auto-completion index file (.autoc) from a list of input files.

Usage: build_autoc stem input_file ... [-collection name -profile name] [-partials] [-label_organics] [-debug]
       e.g. build_autoc index example.csv
       where example.csv will be sorted and indexed into index.autoc.  Input_file(s)
       must end in .csv, .suggest, or .cfg

      -profile <name> - generate scoped .autoc file for the specified
                        profile. A previous run of build_autoc must have
                        been called with -index.
   -collection <name> - generate scoped .autoc file for the specified
                        collection. Both -profile and -collection need
                        to be specified when generating scoped suggestions
            -partials - this version allows multi-word organic
                        suggestions to be triggered either from the full
                        suggestions or from trailing word sequences.  E.g.
                        'big fat cat' triggered from 'fat cat' and 'cat' as
                        well as the full string. This option turns that on.
      -label_organics - present a category label for all the organic completions
      -sample <val>   - Sample postings of suggestion terms, to handle large
                        collections, <val> ranges 0 - 300; speeds up processing
                        with the effect of sampling the suggestions.
                        (1/val postings are used).

build_autoc supports the building of a single .autoc file from multiple input
files of the same or different types.  Files with very simple
format can be combined with hand-crafted files containing
complex actions.  Completion weights from a .suggest file
are automatically determined, while they can be manually specified
in a CSV file.  Completion weights from Best Bets
default to 100.

Note: this binary requires query processor options to be set via the environment
and the calling of it directly from the command line or via Funnelabck workflow
is not supported.
.suggest files built by build_spelling_index can be supplied as
input.  Reasons for doing this include taking advantage of an index
optimised for completion purposes; and integrating automated spelling
suggestions with hand-crafted entries.

Input files with .cfg suffix are no longer supported

Each line of a .csv file must contain eight fields (7 commas),
corresponding to: key, weight, display, display_type, category,
category_type, action, and action_type.  Fields except key and
weight may be empty.
Two meta characters are recognized within a field: backslash and
double quote.  These are handled as follows in the two cases:

(A) Unquoted text: A single backslash is not passed through, while
the character following it is passed through without applying
any tests. This means that a double backslash in input leads to
a single backslash in output and that commas or double quotes
preceded by a backslash do not have their normal meaning.
(B) Quoted text:  The double quotes beginning and ending a quoted
section are not passed through.  Within a quoted section a double
quote may be passed through by either doubling it ("") or by
preceding it with a backslash (\").

By these means it is possible to pass through HTML and/or JSON
containing quotes and/or commas

7. build_match_only_index

Purpose: create a match only index, which build_autoc can use  to build
profiled query suggestions.

Usage: build_match_only_index stem

8. build_spelling_index

Purpose: To build a spelling suggestion file (.suggest/.suggest2) for a collection.

Usage: build_spelling_index index_stem num_thresh [<metadata_class_names> [[<lexiweight>] [[<blacklist_file>] [<whitelist_file>]]]
       e.g. build_spelling_index index 2 [@,t,c]
       where the listed comma separated metadata class names,
       '@,t,c', are the ones to be scanned for
       suggestions.  '@' means use the .anno file.  '%' means use
       unfielded words from index. lex.  + means use phrases from
       index.phrases (if present).  If no fields are listed, "@,+,t,%"
       is assumed.
       num_thresh - minimum weight of suggestions recorded in suggest index
       lexiweight - controls the weight of lexicon suggestions relative
         to annotations.  wt = lexiweight * sqrt(df) (dflt lexiweight = 1.00)
       blacklist_file - manual list of suggestions which should NOT be included
       in the index. (one per line)
       whitelist_file - manual list of suggestions to include in the index.
       (one per line.)

9. csv2ctest

Purpose: To convert a tuning file in CSV format into a C-TEST file for use with e.g. FineTune.

Usage: csv2ctest: infile.csv [-utils=recip|-utils=equal] [-queryweights]

   Output in C-TEST format will be in infile.ctest

The input file is assumed to be a syntactically correct comma separated
value (CSV) file in which cells are separated by commas.  Double quotes
around all or part of a cell allow inclusion of commas.  The quotes are
stripped off before processing.  The input file may contain comment
lines starting with a hash.

The first column in infile.csv is always assumed to contain a query.
If no options are given, then the remaining columns contain desired
answer URLs for that query, in descending order of utility.  Utility
scores start at 4 and then gradually decline to 1: 4, 3, 2, 1, 1, 1 ...
This behaviour may be modified as follows:

  -utils=equal   - All of the answers are given equal utility values.
  -utils=sqrt    - Utility values drop off as 1/sqrt(rank).
  -utils=recip   - Utility values drop off faster -- as 1/rank.

  -queryweights  - if this is given, the second column is expected to
                   contain the numerical weight associated with the query
                   and the remaining columns contain the answer URLs

10. dump_annotation_file

Purpose: To display the contents of an annotation index in geek-readable form.

Usage: dump_annotation_file <annotationfile>

11. dump_autoc

Purpose: To display the contents of a query completion file in geek-readable format.

Usage: dump_autoc <stem|collection|autoc_file>

12. dump_suggestion_file

Purpose: To display the contents of a spelling suggestion file in geek-readable format.

Usage: dump_suggestion_file <index_stem>
 - dumps contents of <index_stem>.suggest

13. get_docnum_from_url

Purpose: Map a URL to that document's number within an index stem.

Usage: get_docnum_from_url <index_stem> <url>

Prints the docnum for a given URL to standard out.
Prints "notfound" if the URL is not found.
  <filestem>  - the common prefix (including path) of the index files
  <url>       - the URL to look up the document number for

14. get_url_from_component_document_pair

Purpose: Within an index, output the URL of the document identified by component number and document number.

Usage: get_url_from_component_document_pair <index_stem> <component_number> <document_number>
Warning:  Doesn't handle nested .sdinfo files.  (Hierarchical meta collections.)

15. get_url_from_docnum

Purpose: print the URL of a document in a primary index, given its URL. Inverse of get_docnum_from_url.

Usage: get_url_from_docnum <index_stem> <doc_num>

16. harvest_anchortext

Purpose: Extract a subset of entries in a list of anchors.gz files which match a specified pattern.

Usage 1: harvest_anchortext -targ|-text|-any|-source pattern anchor_text_file ...

Usage 2: harvest_anchortext -noneps <affiliates_file> anchor_text_file ...

Extracts a subset of lines in the anchor_text_files.  The composition
of the subset depends upon the match_type argument as follows:

-any - Any line (source or target) which matches pattern
-targ - Any target line whose URL target matches pattern
-text - Any target line whose anchortext matches pattern
-source - Any source line which matches pattern

+ In usage 2, links within the same SECD (single-entity-controlled-domain)
  are suppressed, as are links between affiliated pairs of hosts listed in
  the affiliates_file. If there is no affiliates_file, use '-'.

+ Whenever a target line matches the corresponding source line is also output.
+ Whenever a source line matches its corresponding target lines are also output.
+ NOTE: nepotistic links are included unless -noneps is used.

17. hierarchical_navpaths

Purpose: Extract hierarchical navigation paths from a list of anchors files.

Usage: hierarchical_navpaths <stem> [-verbose] [<anchor_text_file> ...]

Reads <stem>.anchors.gz, plus any additional anchortext files to
identify hierarchical navigation paths (HNPs).  These are output
to <stem>.hnp.anchors.gz in standard anchors.gz format:
<target_url> --- [H]<concatenated anchors from path>

    1. inter-host links are ignored.
    2. -verbose prints the actual HN paths to stdout.
    3. All targets in the .hnp.anchors file have http://hnp as source.

Warning: Not ready for use. Development of this utility is incomplete.
Purpose: Analyse a list of anchors.gz files and report on frequencies of inter-host links.

Usage: host_host_link_counts [-targ|-source <pattern>] [-report] <stem> [anchor_text_file ...]

Reads the anchor_text_files and outputs a table of host-host links,
in descending order of link count.   By default, all lines are
processed, but a pattern can optionally be applied to either
targets or sources.

If -report is given, short and full HTML reports will be generated.

-targ - Process only links whose target host matches pattern
-source - Process only links whose source host matches pattern

Nowadays, the first option not starting with a - is an index stem.
A file <stem>.hosts is created with a table of host-related feature
scores which can be used in ranking.  The order of entries must
correspond to the hostnum order assigned by padre-iw.

+ NOTE: within-host links are excluded.

19. padre-arg-sw

Purpose: To help with conversion of padre-sw argument lists from old to key=value format

20. padre-cc

Purpose: To build an index.collapsig file to permit use of collapsed rankings.

Usage: padre-cc <index_stem> [-collapse_control=<string>] [-debug=on]
   Utility for building a .collapsig file of collapsing
   signatures.  If no control_string is given, a one-column
   file is built using the signatures from the .textsig file.

   The collapse_control string must consist of sets of sequences of
   metadata class names. Each set should be surrounded by square
   brackets, and sets should be separated by commas. Metadata class
   names are the elements of the sets and must be separated by

    The characters $ and # may be used as special metadata class
   names and represent document summarisable text and
   document URL respectively.

     In future, it is planned to allow special metadata class
   names to be followed by a regular expression,
   indicating that only the part of the metadata string which matches
   the regex should be used in calculating the signature.

   Example current control string: '[$],[t,a]'.  In this case the .collapsig
   will have two signatures per document: Column 0 is the normal document
   signature and column 1 is a signature derived from the concatenation of
   metadata fields t and a, in that order.

21. padre-ct

Purpose: Report on the titles in a PADRE index.  Eventually to improve them.

Usage: padre-ct <index_stem>

Warning: Development of this utility is not yet complete.

22. padre-cw

Purpose: To check the correctness of an index, compare two indexes, or display postings for a term within and index.

Usage0: padre-cw -v - print PADRE version
Usage1: padre-cw stem1 stem2 [-io] - Compare two indexes.
        -io means ignore diff.s in offsets into .idx
Usage2: padre-cw stem1 -show term - show postings for term.
        Also shows term before and afterward. (if applic.)
Usage3: padre-cw stem1 -check [-stemsuff] [-show_all]- Check index files for stem1 (default)
        use -stemsuff <suffix> to supply an additional suffix for the .idx and dct files
        use -show_all to print every terms summary information.

23. padre-di

Purpose: To display the metadata for documents in an index.  (main purpose)

Usage: padre-di <index_stem> [-check]|[-trecids]|[-metao [<docno>]][-meta [<pattern>] ] | [-metad [<pattern>] ]
-check - check whether the document table appears to be internally consistent

-trecid - make a mapping between trec DOCNO stored in title field and URL

-meta [<pattern>] - print title and metadata information for each document
                    whose "URL" contains pattern (case-insensitive)
                    If no pattern is given, all docs are shown, in collection order.

-metad          - as for -meta but show document numbers.

-metao          - as for -meta but show all documents, in collection order starting
                  from docno (default zero).

-doc_per_meta   - prints in JSON the number of documents each metadata class appears in.

default - read in URLs and look them up, using sorted table

24. padre-do

Purpose: Print a permutation of the document numbers in an index corresponding to descending static score.

Usage: padre-do <stem> <docorderfile> [-deb] [-cool_param ...]
Output is a list of docnums in descending order of cool score,
printed to docorderfile.  cool_param values are expected to lie in 0 - 1.
Default values are the same as for padre-sw though. Of course,
query-dependent cool values cool0, 7, 12, 15, 16, 17, 18, 19 are ignored
because there is no query.

25. padre-fl

Purpose: Display or operate on the document flags in an index.

Usage1: padre-fl <index_stem> [-clearall|-clearbits|-clearkill|-killall|-show|-sumry|-quicken]

Usage2: padre-fl <index_stem> <file_of_url_patterns> [-exactmatch] -unkill

Usage3: padre-fl <index_stem> <file_of_url_patterns> [-exactmatch] -kill

Usage4: padre-fl <index_stem> <file_of_url_patterns> [-exactmatch] -bits hexbits OR|AND|XOR

Usage5: padre-fl <index_stem> -kill-docnum-list <file_of_docnums>

Usage6: padre-fl -v

Note: Specify '-' as the file of url patterns to supply a single URL to standard input.

26. padre-gs

Purpose: Display or manipulate document gscopes in an index.

Usage0: padre-gs -v|-V|-help   # print version info or detailed help
              on types of instructions and on program operation.
Usage1: padre-gs index_stem -clear   # clear all gscopes

Usage2: padre-gs index_stem -show   # show all gscopes

Usage3: padre-gs index_stem file_of_instructions [-separate] [other_gscope]
        [-regex|-url|-docnum] [-verbose] [-quiet] [-dont_backup]

      * index_stem may also be the name of a collection
      * file_of_instructions may be '-' to accept instructions from stdin
      * -separate indicates that gscope changes should be made to a
        copy of the .dt file first, and then copied over the original file
        when changes are complete. In this mode the number of gscope bits
        can NOT be expanded you will be required to ensure enough is available.
      * other_gscope specifies a gscope to be set on documents which
        end up with no gscopes set.
      * By default instruction patterns are expected to be regexes
        but this may be made explicit with -regex or altered with -url
        or -docnum.  Use padre-gs -help to obtain more information about
        instruction formats and pattern types.
      * gscope names may consist of alphanumeric ascii characters up to a length
        of 64 characters.
      * -dont_backup prevents backing up of the .dt file
      * -quiet don't show the before and after summary of gscopes

27. padre-i4u

Purpose: Display aggregated information about a URL from a PADRE index.

Usage: padre-i4u -v | padre-i4u stem=<stem_or_collname> [fields=<alnum_string>] [debug=<int>] [iters=<int>] [format=json/old] [coll=collection_name] url=<url> ...
Note: The functionality is implemented by a dynamic library which is usually called directly.
coll= option should be set to the name of the collection corresponding to the stem= option

28. padre-iw

Purpose: Index a collection of documents

Usage1: padre-iw -V|-help|-helpadoc|-ixform            (print version or help info.)
Usage2: padre-iw [-f|-tar|-reo<pf>] <dir>|<file>|<url> <filestem> [<option>|<tfdir> ...]
Usage3: padre-iw -secondary_update <dir>|<file> <filestem>
<pf> is a text file containing a permutation of the document numbers in the original index.
<dir> is a hierarchical directory of optionally gzipped files.
<file> contains a list of names of optionally gzipped files.
-f says that <file> is a single datafile to be indexed. For historic reasons
-tar means the same as -f.
     Files to be indexed may be tar or WARC files (optionally gzipped).
     Note that individual files in a tarfile are expected to be uncompressed.
     text.  Gzipped files, unfiltered PDFs etc. are not supported yet.
-reo says that <file> is the stem of a previous index to be
     reordered and reindexed.   <pf> is a text file containing
     a permutation of the document numbers in the original index.  Eventually,
     it may be possible to compute the permutation internally. For now, it
     must be specified via <pf>.
<filestem> prefixes the names of output files.
<tfdir> is the dir. in which tmp files will be writ.
-secondary_update creates a secondary index using the data directory specified, and using the options used in creating the primary index.

Available options:

A. Getting information about PADRE and its operation.
  -V       - Print PADRE version number and exit.
  -ixform  - Print index format version created by this indexer exit.
  -help    - Print this list and exit.
  -helpadoc - Print this list in asciidoc format and exit.
  -debug   - Generate debugging output.
  -show_each_word_indexed - For debugging.  Show each word occurrence (with field) as it is indexed.
  -show_each_word_to_file - For debugging.  Print each word occurrence (with field) to <filestem>.words_in_docs
  -hashlog - Create a .hashlog file with incremental hashing stats.
  -quiet   - Use terse logging.
  -ankdebug - Generate debugging output relating to anchortext.
  -termdeb<term> - print debugging messages relating to the indexing of <term>.

B. Controlling what is indexed.
  -nometa   - Don't index any metadata except t, d and k (titles, dates and links).
  -nomdsfconcat - Don't concatenate strings in the mdsf file. Record first only. (Others are still indexed.)
  -diwimuu - Don't index words in made-up URLs (those constructed from filepath).
  -dias    - Don't index link anchor source as part of source documents (<a> only).
  -ibd     - Index all documents even if they appear to be binary.
  -ixcom   - Index words in HTML and XML comments.
  -select<num1>,<num2> - Index every num1th file/bundle starting from
            num2th(from zero).
  -select-doc-in-bundle=<interval>,<offset> - Index every <interval> document
            within a bundlestarting from <offset> (which starts at zero).
            Only works with warc store.
  -tarpat<regex> - Filenames in a tarfile being indexed must match regex. Default is match-everything.
  -csv=<fsep><skipfirst>[<quote>] - Deprecated. Use the CSV to XML filter instead. Files which are
                            not clearly something else
                            are assumed to be CSV format.
                          fsep is ascii field separator, typically comma.
                            (tab is represented by t.)
                          skipfirst is either y or n, telling padre whether the first
                            line in a CSV file should be skipped.
                          quote is the character used to quote strings in fields
                            which may contain separators.  (You probably have to
                            escape it on the command line.)  If not specified,
                            no quote character is defined.  To include a quote
                            character within a quoted section, the quote may be doubled.
  -csv_fields=<comma_separated_descriptor_list> - Deprecated. Use the CSV to XML filter instead.
                          This is a list of comma
                          separated descriptors describing how to index each column of
                          the csv file.
                          To index terms in a column as document text use '-'.
                          To index terms in a column as metadata use the format:
                               <metadata class name><content type>
                          To skip terms in a column use 'X'.
                           For example: 't1,-,X', would set the first column to title,
                          the second column would be indexed as document content and the third
                          column would b skipped.
                           Content-type defined in this argument should be the same as the content type in
                           the metadata mappings
  -check_url_exclusion=<on|off> - URLs matching url_exclusion pattern will not be searchable.  (Default on.)
  -url_exclusion_pattern=<regex> - exclusion pattern to use if URLs are vetted.  (Default 'file://$SEARCH_HOME/')
  -filepath_exclusion_pattern=<regex> - exclusion pattern to use if files are to be excluded from indexing
            on the basis of the filepath.  If applicable, this is more efficient than excluding by URL
            because the URL can't be finally determined until the content has been scanned. (Default: not set)
  -index_subversion_dirs - Normally the .svn directories created by
       the subversion version control system are not indexed. Override this default.

C. Controlling how things are indexed.
  -noax    - Don't conflate accents.
  -unimap=<mapname> - specify a Unicode mapping to be applied when indexing
                      and when query processing. Supported values:

  -deutsch=<i> - How much extra processing is done for umlaut and sz.
             0 - none.  München is indexed as München and Munchen

              2 - As for 1 but also Muenchen is indexed as München, Muenchen and Munchen
             (As a side-effect to allow for compounds, SORT_SIGNIF is increased to 40
  -nz=<i> -      How much extra processing is done for Māori.
             0 - none.  Māori and Mäori are indexed as Māori or Mäori resp. and Maori (Dflt)
             1 - Māori is indexed as Māori, Maaori and Maori
                 Mäori is indexed as Mäori, Māori, Maaori and Maori
  -no_cjkt_grams - Suppress the indexing of bigrams/unigrams in CJKT text.  It is assumed that
                   said text has been pre-segmented into words, and that normal word-based indexing is needed.
  -QL_depth=<i> - Activate quicklinks on default pages of up to depth i. Use internal QL                  defaults.  (Dflt 0 = Off)
  -QL_config=<f> - Activate quicklinks. Read quicklinks configuration options from
                  file f.

  -forcexml - Use the XML parser on all documents.
  -case    - Store case information in postings. Currently unsupported. Note that setting
             this reduces the approximate max number of unique terms from ~950M to ~240M.

                  3 - dynamically generated links from such a host.
  -nep_cachebits=<i>  - Don't let the low-value link cache grow above 2^i
  -noaltanx - Don't index image alt as anchortext when an image is an anchor.
  -nosrcanx - Don't index image src as anchortext when an image is an anchor.
  -BL<f>   - <f> is a file of source URL patterns from which links should be ignored or treated with suspicion (Blacklist).

             e.g. -->
             Links to an affiliated SECD are classified as within-domain.
  -RP<f>   - <f> is a file of CGI parameters which should be removed from source and target URLs.
           - padre generates a regular expression from the lines in <f>.

                                     for metadata. These phrase terms can be used to speed up queries like a:"$++ foo bar $++".
                                     Phrases will only be created if indexing of field boundaries is enabled, which it is by default.
                                     Disabling may reduce indexing time and index size.

F. Controlling which index files are generated.
  -nomdsf  - Suppress generation of the .mdsf file.

  -cleanup - Remove superfluous files from the index directory after index has completed.

G. Setting size limits.
  -GSB<n>  - How many gscope bytes to allow for. Default/Min: 8/2.
NOTE: This setting is no longer required as gscope bits are now auto-sized.
  -big<N>    - Multiply word table sizes by 2^N from base of 256K.  Default table size is 8M (ie. -big5).

  -W<num>  - Index-writing window will be <num> MB (Larger windows mean faster indexing at the expense of using more RAM). Default for a 64bit system is 2800
  -MWIPD<num>- Maximum words indexed per document (excluding anchors). By default all words are indexed
  -maxdocs<num>- Maximum no. of documents to index. Others are ignored.
  -mdsfml<n> - Set the number of bytes used for MetaData Summary Field Maximum Lengths. Fields larger than this number will be truncated. Default is 2048.
  -lock_string_mod_mode=[legacy|raw] - Sets how padre should modify the lockstring before it is stored, 'legacy' mode which removes some characters, replaces unquoted commas into new lines and removes consecutive new lines. 'raw' mode stores the lock string as is up to the first null.
  -99%    - Limit on how full the word hash table can get.

H. Special indexing modes.
  -duplicate_urls=flag|ignore (Default is flag.)
            - Documents whose URL checksum is identical to that of another document
              are normally flagged and suppressed from results.
  -urlchecksums=case_sensitive|case_insensitive (Default is case_insensitive).
  -paidads  - If set, documents known to contain paid ads will be flagged specially (with the DOC_HAS_PAID_ADS flag).
  -doc_feature_regex=<Regex> - Documents matching the supplied pattern will be flagged as DOC_MATCHES_REGEX.
             The presence or absence of this feature can be used in the ranking function, controlled by cool29 and cool30.
  -iolap   - Overlap reading of bundles with processing them.
  -utf8input - Assume all input files whose charset is not specified are UTF-8 encoded. (Default is WINDOWS-1252.)
  -isoinput - Assume all input files whose charset is not specified are ISO_8859-1 encoded.
  -force_iso - Forcibly assume all input files are ISO_8859-1 encoded.
  -URLP<str> - When storing documents URLs, prepend <str>. (This is only used if the document does not indicate it's own URL with a BASE HREF element, such as in local collections)
  -lmd       - HTTP LastModified date takes priority over metadata dates.
  -lmd_never - Completely ignore HTTP LastModified dates.
  -ignore_link_rel_canonical - Ignore canonical URL declarations in HTML link elements.
  -ignore_noindex - Ignore robots noindex meta element.
  -DT<str>   - Interpret <str> as start of new doc within bundle. (Not a regular expression).
               (note that there is a separate mechanism for XML).
  -annie[<exec>] - After normal indexing is complete, attempt to build an annotation index (annie)
                   and a spelling suggestion file.
                   Default executables are annie-a and build-spelling-index from whence padre-iw was run.
  -speller[<exec>] - Allows the explicit specification of a spelling_index builder to run after annie-a.
  -spelleroff - turns of spelling-index building even if annie-a runs.
  -spelling_threshold<i> - Annotations with fewer than i occurrences will not be considered
                           as spelling suggestions.  (dflt 1)
  -bigweb  - Space saving option for bundled large crawl indexes. Roughly equivalent to:
             -nomdsf -big8 -MWIPD2000 -W6000 -SORTSIG16 -nep_action=2 -nep_limit=2
             -nep_cachebits=20 -chamb64 -RSTXT2000 -mule128 -noaltanx -nosrcanx -nometa -quiet
              * A shorter average wordlength is assumed.
              * You can add e.g. to cut anchor processing time.
              * (Don't forget to make dupredrex.txt in index directory.)

I. Miscellaneous options.
  -O<name> - <name> is the name of this organisation.
  -T<path> - Specify a large temporary filespace for use by the indexer.
  -redis_host=<str> - Hostname/IP of a Redis server where progress status should be written
  -redis_port=<i> - Port of the Redis server. Default is 6379

S. Security options.
  -security_level=<i> - Any non-zero value requires every document to have at least one lock. If set to 1 documents without locks will be excluded, if set to greater than 1 indexing will stop.
  -security_mindocs=<i> - Must be at least this number of docs with at least one lock.

     *** See also url_exclusion options in Section B above.

29. padre-mi

Purpose: To merge a list of PADRE indexes into a single such index.

Usage: padre-mi outstem instem instem ... [-overwrite] [-cleargscopes]
   -overwrite overrides protection against destroying existing outstem
   -cleargscopes clears all set gscopes from the resulting index

Make a merged index (outstem) from the list of at least two input indexes.

This version assumes that input indexes have exactly the same format,
i.e. that the index format strings are the same and that they have
identical numbers of gscope bits, numerical metadata fields and so on.
Future versions may check this compatibility, but currently exact compa-
tibility is assumed.  All manner of pestilence may descend upon you if
you use padre-mi on incompatible indexes.  You have been warned :-)

30. padre-qi

Purpose: To setup a query-independent-evidence file for use in query processing.

Usage: padre-qi index_stem file_of_url_patterns dflt_score [profile_name] [-verbose]

 - if a profile name is given, qiefile will be stem.qie_profile

Each URL in the index is matched against the patterns, in the
order in which they are listed in the pattern file.  Once a match
is found, matching ceases for that URL.  This behaviour can be
exploited to apply a general pattern (later in the file) if
no more specific pattern (earlier in the file) matches.
  To achieve exact matching use ^ (matches start of URL) and
$(matches end of URL

Lines in the patterns file consist of:

<qie score> <url-pattern>

qie-score  - a floating point number (assumed normalised to the range 0-1),
             specifying the qie score to be applied.

url-pattern   - a perl5 regular expression to be matched against name
                 strings in the .urls file (usually URLs).

0.25  ^(https://)?[^/]*
1.0   ^(https://)?[^/]*
0.25  ^(https://)?[^/]*
0.25  ^(https://)?[^/]*

31. padre-qs

Purpose: To generate query suggestions given an index and a partially typed query.

Usage: padre-qs -v | padre-qs stem=<stem>|collection=<collname> partial_query=<partial_query> [alpha=<f>] [show=<d>] [fmt=xml|json|json++] [callback=foo] [sort=0|1|2] [profile=<profile>] [debug=0|1|2|3], e.g.
Note: The functionality is implemented by a dynamic library which is usually called directly.
padre-qs stem=/opt/funnelback/data/abc/live/idx/index partial_query=kevi alpha=0.5 show=10
  - sort=0 (by weight), 1 (by length), 2 (in alphabetic order), 3 (by weighted combo of weight and length).
  - fmt=json => simple JSON array of suggestion strings;
       =json++ => full JSON object with all fields shown.
  - callback=foo => In JSON or JSON++ output will wrap
         the response with the supplied callback (for JSONP).
  - show=<d> => how many suggestions to show.
  - alpha=<f> => if sort=3, score = alpha * weight + (1 - alpha) * length_score.

     . html (default)
     . embedded (incomplete html suitable for embedding in another html document)
     . text
     .textsigs (generate stem.textsigs file suitable for neardup detection.)
If -titleonly is given only the document titles are output. (not applic. to textsigs)

If a starting document number or URL is given, output commences
only when that point in the file is reached.  Output continues
to the end of the file unless num_docs_to_show is given.
If urlpat= is given, only documents whose URL matches the pattern are
considered for display.  Case-sensitive unless specified otherwise
in the pattern.  Don't include 'http://' in the pattern.

37. padre-sw

Purpose: Process queries using a PADRE index.

                                          e.g. if metadata 'author' has 'Bob Ada|Bob|Bob' in two documents the resulting
                                          counts would be 'Ada': 2, 'Bob': 6. As this counts indexed terms long terms may
                                          be truncated depending on the indexer options used. To count fields 'a' and

                                          Syntax: -countUniqueByGroup=[classToCount]:[groupBy],[classToCount]:[groupBy].
                                          Example: -countUniqueByGroup=[author]:[project] would show us the number of
                                          authors contributing to each project. classToCount is a regex and will be
                                          expanded to all matching metadata classes e.g. [author.*]:[project] might
                                          expand to -countUniqueByGroup=[author]:[project],[authors]:[project].  [Not CGI]

                                          facets). If metadata 'author' has 'Bob Ada|Bob|Bob' in two documents the counts
                                          would be 'Bob Ada': 2 'Bob': 2. To count fields 'a' and 'c', set this to
   -rmrf=<S>                            - Numerical and geospatial fields listed will have their ranges calculated in

   -sum=<S>                             - The sum of a numeric metadata in result set. Syntax: -sum=[sumOn],[sumOn].
                                          Example: -sum=[size] would sum all values of numeric metadata 'size' in the
                                          result set. Note sumOn my be a regex which expands sumOn to all matching
                                          metadata classes e.g. -sum[size.*] might expanded to -sum=[sizeInKb],[sizeLoc].  [Not CGI]
   -sumByGroup=<S>                      - The sum of a numeric metadata by a group. Syntax:
                                          -sumByGroup=[sumOn]:[groupBy],[sumOn]:[groupBy]. Example:
                                          -sumByGroup=[size]:[project] would sum all values of numeric metadata 'size'
                                          grouped by 'project' giving output project 'Foo' has size '128', project 'Bar'
                                          has size '12'. Note sumOn my be a regex which expands sumOn to all matching
                                          metadata classes e.g. -sumByGroup[size.*]:[project] might expanded to
                                          -sumByGroup=[sizeInKb]:[project],[sizeLoc]:[project].  [Not CGI]

   -sco=<S>                             - <n>[<classes>] Set doc scoring mode to n, using the classes specified.  Most
                                          common values: 0 - score using doc text only ;  1 - no scoring.  Produce an
                                          unordered set of results ; 2 - score using anchortext and URLs as well,
                                          upweight titles (or whatever fields are configured with -specf). For example to

   -static_cool_exponent=<F>            - Control the extent to which static scores are attenuated with length of query.
                                          0 => no attenuation; 1 => max attenuation. Attenuation by len ** -f. (range 0.000000 - 1.000000)

   -use_secds=<B>                       - When working with domain-importance features in ranking, use SECDs if value is
                                          on, and raw domain names otherwise.
   -vsimple=<S>                         - Very simple ranking. If set to 'on', equivalent to -sco=0 -cool=off -SSS=0

                                          terms in one or more of the implicit fields listed here.  For example,
                                          specifying '[K,k]' will stop the query 'Monica Lewinski' matching a document
                                          solely because of click data or referring anchortext.

                                          previous result by multiplying by the factor specified. The penalty stiffens
                                          with more repetition. Setting to 0 turns this off. (dflt 0) (range 0.000000 - 1.000000)
   -title_dup_factor=<F>                - The query processor will penalise a result which has exactly the same title as
                                          a previous result by multiplying by the factor specified. The penalty stiffens
                                          with more repetition. Setting to 1 turns this off. (dflt 0.5) (range 0.000000 - 1.000000)

                                          active; 2 bit - selects whether MINRESULTS mode is used or not. During internal
                                          testing, every odd numbered document in the original ranking is arbitrarily

38. padre-topk

Missing required argument -input=<input file>
List the top-k most frequent items
Usage: padre-topk -input=<input file> [-capacity=<integer>] [-k=<integer>]

  * -input: is the file of items where each item is delimited by new line
  * -capacity: this is the limit as to the number of items that will be held in memory at once.
  * -k: this is the number of items that will shown at the end.

Efficiently (compared to some other algorithims) estimates the count of the most frequent top-k items
e.g. for a,b,c,a,b,a the top-2 would be a with a count of 3 followed by b with a count of 2

39. pan-look

Purpose: Efficient location of all lines in a sorted text file which match a prefix.

Usage: pan-look <prefix> <file name>

40. phrasefinder

Purpose: Extract frequently occurring word tuples ('phrases') from a collection.

Usage: phrasefinder <stem> [-unco] [-hash_limit=<i>] [-num_to_show=<i>] [-max_tuple=<i>] [-debug]

phrasefinder reads the .results file of <stem> and locates candidate word tuples
('phrases') up to a configurable maximum length.  Phrases are sequences
of up to max_tuple words which are unbroken by anything other than space.

Candidates are stored in a hashtable and counted.  A limit of
hash_limit candidates is stored.  Once this is reached, the program
exits. (Useful for testing or for limiting execution time and virtual
memory requirements.)  When processing finishes, the top num_to_show
candidates are sorted in descending order of frequency and output in
<stem>.phrases, in the same format as the .lex file, with word breaks
represented by hyphens.

41. run-with-flock

Purpose: Runs a command with a exclusive file lock held.

Usage: run-with-flock file_lock_path lock_acquired_path cmd arg0 arg1 ... argn

 This will open (and create) 'file_lock_path' and then will take a
exclusive file lock on the path after that it will create the file:
'lock_acquired_path', if all of that succeeds then the given command will be
executed while the lock is held.

42. show_annotations_for_doc

Purpose: Given an annotation index, summarise the annotations applied to a given URL.

Usage: show_annotations_for_doc <index_stem>|<collection> <URL>|<URL64>|<DOCNO> [-csv|-html|-xml]
  - Show the annotations applying to the specified URL and their weights.
  - Don't forget to quote or escape shell metacharacters in a URL!
  - Default output format is XML.

43. url_tagger

Purpose: Apply the tags in a tag mapping file to a PADRE index.

Usage1: url_tagger stem (-clear|<url-tags-file>)

Usage 2: url_tagger -v

url_tagger -clear clears all tags from all documents in the index
url_tagger <url-tags-file> takes an url-tags file and applies it to
the relevant entries in <stem>.results.

url_tagger -v shows version information.
Lines in the url-tags file are in the form: <url> <comma-separated-taglist>
It is assumed that <url> contains no space and tags contain no commas.
