Alan Woodward updated LUCENE-6226:
----------------------------------
Attachment: LUCENE-6226.patch
New patch.
Rather than getting positions directly from the Scorer, this goes back to
Simon's original idea of having a separate per-scorer IntervalIterator. We
have an IntervalQuery that will match a document if it's child scorers produce
any matching intervals, and the notion of an IntervalFilter that allows you to
select which intervals match.
Query.createWeight() and IndexSearcher.createNormalizedWeight() take an enum
based on Adrien's idea. Scorers that don't support iterators (which at the
moment is all of them except TermScorer) throw an IllegalArgumentException.
TermWeight.scorer() will throw an IllegalStateException if the weight has been
created with DOCS_AND_SCORES_AND_POSITIONS but no positions were indexed.
> Allow TermScorer to expose positions, offsets and payloads
