> With the cutover to per-segment searching, CustomScoreQuery is not really
> usable anymore, because the per-doc custom scoring method (customScore)
> receives a per-segment docID, yet there is no way to figure out which segment
> you are currently searching.
> I think to fix this we must also notify the subclass whenever a new segment
> is switched to. I think if we copy Collector.setNextReader, that would be
> sufficient. It would by default do nothing in CustomScoreQuery, but a
> subclass could override.
