[GitHub] [lucene] pminkov opened a new pull request, #939: Use similarity.tf() in MoreLikeThis
pminkov opened a new pull request, #939:
URL: https://github.com/apache/lucene/pull/939
### Description
MoreLikeThis picks terms by their TF-IDF score. The TF part of the score was used by taking the term frequency directly, without applying a square root through ClassicSimilarity.tf(). The result of this is that how common a term is in an input can have too much weight on whether it's selected as a search term. This can make more stop words make their way into the final query.
