Adrien Grand commented on LUCENE-6226:
--------------------------------------
Maybe we should not allow collectors to consume positions (yet) (ie.
Collector.postingsFlags() should remain Collector.needsScores())? Positions can
only be iterated once while it's quite typical to wrap several collectors into
a single one using MultiCollector. So if you have several collectors that need
positions in a MultiCollector, it would only work fine for the first one?
Also why does TermScorer track the number of times that nextPosition() has been
called in order to return NO_MORE_POSITIONS? The wrapped PostingsEnum should
already take care of it?
> Allow TermScorer to expose positions, offsets and payloads
