Robert Muir commented on LUCENE-6244:
-------------------------------------
This latest patch looks nice at a glance.
Can you explain this comment a bit more, I'm not sure I understand:
{noformat}
Because things are structured differently, I lost the feature that we confirm
at most one clause per doc
{noformat}
Why do we pass needsScores to these disjunctions? It seems to only optimize the
case where someone doesnt needScores but calls freq() anyway, and I don't think
we should optimize that. DisjunctionScorer already defers all scoring/freq so I
don't think it needs this boolean at all.

> Like we just did on exact phrases and conjunctions, we should also support
