Alan Woodward commented on LUCENE-8306:
---------------------------------------

I think of it more as adding flexibility.  With this API you can either 
highlight whole matches, or individual parts of matches, or any combination in 
between that you like.  And it's a pretty minimal addition - one extra method 
and a FunctionInterface.  And seeing as the whole point of the Matches API is 
to help highlighting, I think it's worth it?

> 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.
