Subject [jira] Commented: (LUCENE-1272) Support for boost factor in MoreLikeThis
Date Tue, 14 Jul 2009 16:49:14 GMT


Michael McCandless commented on LUCENE-1272:

Patch looks good.  I'll just add copyright header to the new unit test, and change the "assertTrue"
that compares the floating points boosts, to assertEquals w/ an epsilon.  I'll commit shortly.

> This is a patch I made to be able to boost the terms with a specific factor beside the
relevancy returned by MoreLikeThis. This is helpful when having more then 1 MoreLikeThis in
the query, so words in the field A (i.e. Title) can be boosted more than words in the field
B (i.e. Description).
