LUCENE-10229: change the wording a bit.
> Match offsets should be consistent for fields with positions and fields with
> offsets

> This is a follow-up of LUCENE-10223 in which it was discovered that fields
> with
> offsets don't highlight some more complex interval queries properly. Alan
> says:

> It's because it returns the position of the inner match, but the offsets of
> the outer. And so if you're re-analyzing and retrieving offsets by looking
> at the positions, you get the 'right' thing. It's not obvious to me what the
> correct response is here, but thinking about it the current behaviour is kind
> of the worst of both worlds, and perhaps we should change it so that you get
> offsets of the inner match as standard, and then the outer match is returned
> as part of the sub matches.
> {quote}
> Intervals are nicely separated into "basic intervals" and "filters" which
> restrict some other source of intervals, here is the original documentation:
> https://github.com/apache/lucene/blob/main/lucene/queries/src/java/org/apache/lucene/queries/intervals/package-info.java#L29-L50
> My experience from an extended period of using interval queries in a frontend
> where they're highlighted is that filters are restrictions that should not be
> highlighted - it's the source intervals that people care about. Filters are
> what you remove or where you give proper context to source intervals.
> The test code contributed in LUCENE-10223 contains numerous query-highlight
> examples (on fields with positions) where this intuition is demonstrated on
> all kinds of interval functions:
> https://github.com/apache/lucene/blob/main/lucene/highlighter/src/test/org/apache/lucene/search/matchhighlight/TestMatchHighlighter.java#L335-L542
> This issue is about making the internals work consistently for fields with
> positions and fields with offsets.
