Michael McCandless commented on LUCENE-7132:
--------------------------------------------
OK if I put back BQ's bulkScorer, but then use {{new IndexSearcher}} instead of
{{newSearcher}} the first seed above gets further along: the scores agree
before/after forceMerge, but the explanation is still incorrect...
> 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.
