David Smiley commented on LUCENE-6494:
--------------------------------------
I'm looking over your latest patch, with an eye for it's suitability for
accurate highlighting (aka "query debugging"). Ultimately, the "term" needs to
be collected, and it isn't done so by MatchData/SpanCollector now. It seems an
approach would involve a custom SpanCollector subclass that captures the term
-- at least it's passed in already. But SpanCollector is instantiated
internally by PayloadTermSpanScorer, SpanPayloadCheckQuery, and
SpanNearPayloadCheckQuery. I was hoping there would be some way to pass in a
custom one into SpanWeight from the outside; that is/was the case but this API
change removes that. I do think this looks/feels nicer though; but it loses a
capability -- albeit one it only had for a couple days now. What do you think
Alan?

> With the addition of SpanCollectors, we can now get arbitrary postings
> information from SpanQueries. PayloadSpanUtil does some rewriting to convert
> non-span queries into SpanQueries so that it can collect payloads. It would
> be good to make this more generic, so that we can collect any postings
> information from any query (without having to make invasive changes to
> already optimized Scorers, etc).
