You could get the Scorer and call next() yourself; this would avoid scoring. EG something like this:
Weight weight = query.weight(searcher); Scorer scorer = weight.scorer(searcher.getIndexReader()); while(scorer.next()) { final int docID = scorer.doc(); /* do something w/ docID */ } But note that this code is not generally recommended in 2.9 (since it's not operating at the segment level). If your queries contain only SHOULD and up to 32 MUST_NOT clauses, then calling BooleanQuery.setAllowDocsOutOfOrder should improve performance since internally it will use BooleanScorer instead of BooleanScorer2.
