[jira] [Commented] (LUCENE-7498) More Like This to Use BM25

    [ https://issues.apache.org/jira/browse/LUCENE-7498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15632601#comment-15632601 ] 

Alessandro Benedetti commented on LUCENE-7498:
----------------------------------------------

Started the implementation and tests.
The refactor will break down the big MoreLikeThis monolithic class in more cohesive classes with separate tests.
I will keep this ticket up to date.

> BM25 is now the default similarity, but the more like this is still using the old TF/IDF .
>  
> This issue is to move to BM25 and refactor the MLT to be more organised, extensible and maintainable.
> Few extensions will follow later, but the focus of this issue will be :
>  - BM25
> - code refactor + tests
