Dawid Weiss commented on LUCENE-8401:
-------------------------------------
bq. I wonder how interleaved hits should be handled.
Just to throw more ideas here. :)
It'd be another possibility for a pluggable component. One implementation could
resolve overlaps into contiguous fragments, another could create separate
highlights, for example in different colors (or more saturated on the overlap
region). (AAA[C)BBB] overlap would create three regions then, each with a
possibly different highlighting marker: (AAA)(C)(BBB). The latter is useful in
a interesting scenario where highlights come from two or more different sources
(independent queries). Then the passage selector then needs to select window
regions maximizing hit regions from each query and resolve overlaps to
visualize where each query matched (with a different color, for example).

> Jim and I discussed a while back the idea of adding highlighter components,
> rather than a fully-fledged highlighter, which would allow users to build
> their own specialised highlighters. To that end, I'd like to add a
> PassageBuilder class that uses the Matches API to break text up into passages
> containing hits.
