> This is just an exploratory patch ... still many nocommits, but I
> think it may be promising.
> I find the two booleans we pass to Weight.scorer confusing, because
> they really only apply to whoever will call score(Collector) (just
> IndexSearcher and BooleanScorer).
> The params are pointless for the vast majority of scorers, because
> very, very few query scorers really need to change how top-scoring is
> done, and those scorers can *only* score top-level (throw throw UOE
> from nextDoc/advance). It seems like these two types of scorers
> should be separately typed.
