> Should DisjunctionScorer advance more lazily?

> Today if you call DisjunctionScorer.advance(X), it will try to advance all
> sub scorers to X. However, if DisjunctionScorer is being intersected with
> another scorer (which is almost always the case as we use BooleanScorer for
> top-level disjunctions), we could stop as soon as we find one matching sub
> scorer, and only advance the remaining sub scorers when freq() or score() is
> called.
