Alan Woodward commented on LUCENE-8306:
---------------------------------------
I ended up back where [~jimczi] suggested about a month ago. The attached
patch adds two new methods to MatchesIterator:
* label() - allows you to associate the current match with a top-level leaf
query
* getSubMatches() - returns another MatchesIterator over the individual term
positions within the current match
This doesn't expose terms, freqs or payloads. I figure let's try and keep the
API as low-surface as possible for now, and see how far we get with
highlighting.

> 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.
