Alan Woodward commented on LUCENE-8306:
---------------------------------------
Thanks for the review David!
Re label() : yes, that's a good idea, I'll change it to return the leaf query
Re SloppyPhraseMatcher, you're correct, I found some bugs there. We can't work
directly on PhrasePositions because the submatches need to be returned in
order, although I suppose it might be simpler to just have a sorted array of
ords. I'll work something up.
Re TermMatchesIterator.getSubMatches(), I've gone back and forth on this. One
the one hand, yes, it's already a leaf, but on the other I think it will be
simpler for consumers to just assume that the top level matches are for
intervals and the next level are for terms, so for example you can always call
getSubMatches() to find individual terms when highlighting.
> Allow iteration over the term positions of a Match

> For multi-term queries such as phrase queries, the matches API currently just
> returns information about the span of the whole match. It would be useful to
> also expose information about the matching terms within the phrase. The same
> would apply to Spans and Interval queries.
