On very large/busy instances, many requests to More Like This can slow the site down.
- Jira Issues:
- JIVE-11968: Slow request generated from More Like This widget to getMoreLikeThisResultsByType
Identifying the Problem
- Running a busy/large site
The access logs show many slow requests to /__services/v2/rest/morelikethis/2/
We don't intend to make changes to core functionality for this issue, as it affects few sites. Instead, if this issue shows up, we recommend making the following system property changes:
search.mlt.minWordLen = 5
search.mlt.minTermFreq = 4
search.mlt.minDocFreq = 5
Note: Applying these properties will require a restart to take effect.
