This parameter controls whether sitemap.xml files listed in robots.txt are used during a web crawl.

Setting the key

Set this configuration key in the search package or data source configuration.

Use the configuration key editor to add or edit the crawler.use_sitemap_xml key, and set the value. This can be set to any valid Boolean value.

Default value


The default value is false i.e. do not try to process sitemap.xml files during a crawl.


Specify that sitemap.xml files should be used:


With this setting the Funnelback web crawler will check the robots.txt files for each web server that passes the crawl include patterns. If the robots.txt file contains any Sitemap: directives these will be processed, including any sitemap index files and compressed sitemap.xml files.


  • The Funnelback webcrawler will not currently take note of any lastmod elements in the sitemap.xml files - standard incremental crawling can still be used to avoid downloading any content which has not changed, based on its content length.

  • If the crawler.max_individual_frontier_size parameter is defined and non-empty then this will be used as a limit on the total number of URLs that will be extracted from the sitemap file(s) for any individual site.

  • All URLs extracted from sitemaps will be processed in the same way as links extracted while crawling normal web pages e.g. they will be run through the loading policy. This means they will be checked against relevant robots.txt rules, include and exclude patterns etc.
