Robert Muir commented on LUCENE-5452:
-------------------------------------
Cool, maybe we can actually optimize the existing PQ stuff anyway (its not
super-huper-duper optimized). But in general its bounded towards the number of
matching sentences per doc, which is presumably quite small (there is some
paper suggesting more than 5 is not that useful, so I assumed that). I'll take
a look.
The other thing that concerned me (and it may be just fine in your patch), is i
couldn't tell if there was a little O(n^2) as far as fields go (fieldsIn *
fieldsToMatchedFields), and the termsenum/docsenum/etc reuse across same
segment became even more hairier than it is now (and its definitely ugly now).
The final advantage of the "level above" would be, the multi-term highlighting
etc would work for free.
I'm gonna open a separate issue to try to improve some of this existing code,
it was confusing to me just looking at it.

> Like you can do with the FVH, it'd be nice to be able combine matches from
> multiple fields with the postings highlighter.
> Note that the postings highlighter doesn't do phrase matching and doesn't use
> term boosts so some of the FVH's field combining features won't work. It'd
> be nice to get some of them, though.
