[jira] [Commented] (LUCENE-8439) DisjunctionMaxScorer should leverage sub scorers' per-block max scores

["Jim Ferenczi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-8439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16565438#comment-16565438 ] 

Jim Ferenczi commented on LUCENE-8439:
--------------------------------------

Thanks for looking Adrien. I pushed a new patch that factors out a BlockMaxDISI implementation and uses it only if the score mode is set to TOP_SCORES.

 I guess it works well because scores on title dominate the overall score?

Yes, this optim works best when the small field (here title) dominates the overall score.
