Michael McCandless commented on LUCENE-7132:
--------------------------------------------
A bit more progress ... it looks like somehow {{BooleanScorer}} gets confused
and is collecting a window with more than one sub-scorer matching, yet failed
to tell the top collector to reset back to the fake scorer (it's still on a
boosted scorer, I think from a prior window that had only one matching sub,
incorrectly applying a 0.3333 boost).
> BooleanQuery scores can be diff for same docs+sim when using coord (disagree
> with Explanation which doesn't change)

> Some of the folks
> [reported|http://find.searchhub.org/document/80666f5c3b86ddda] that sometimes
> explain's score can be different than the score requested by fields
> parameter. Interestingly, Explain's scores would create a different ranking
> than the original result list. This is something users experience, but it
> cannot be re-produced deterministically.
