    Description

      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.
