Minimum Term Matching in More Like This Queries

[Tim Hearn <ti...@gmail.com>]

Hi!

I'm fairly new to Solr.  Is there a feature which enforces minimum term
matching for MLT Queries?  More precisely, that is, a document will match
the MLT query if and only if at least x terms in the query are found in the
document, with x defined by the user.  I could not find such a feature in
the documentation, and switching to the edismax query parser and using the
'mm' parameter does not work for me.

Thanks!

There is no direct way of retrieving doc based on minimum term match in
Solr. mlm params 'mlt.mintf' and 'mlt.match.offset' can be explored if they
meets the criteria. Refer below links for more details:
http://wiki.apache.org/solr/MoreLikeThisHandler
https://wiki.apache.org/solr/MoreLikeThis

In case you are using lucene library directly,setPercentTermsToMatch()
function can be used from MoreLikeThisQuery class.
Refer code:
https://svn.apache.org/repos/asf/lucene/dev/trunk/lucene/queries/src/java/org/apache/lucene/queries/mlt/MoreLikeThisQuery.java
