push.scheduler.killed-percentage-for-reindex
Background
The percentage of documents which must already be killed in a set of merging generations for the new generation to re-index the merged WARC file (rather than merging the indexes).
A lower value will result in more frequent re-indexing, producing improved ranking at the cost of more computation time per merge. A higher value reduces merge times at the cost of lower search quality, increased disk space usage and slower query processing times.
Setting the key
