Method ScoreSubDocsAtOnce

Override this and return true if your collector (e.g., ) expects all sub-scorers to be positioned on the document being collected. This will cause some performance loss; default is false. Note that if you return true from this method (in a subclass) be sure your collector also returns false from AcceptsDocsOutOfOrder: this will trick BooleanQuery into also scoring all subDocs at once.
