I *think* something close to this would allow you to count the number of docs matching a query without scoring: Scorer s = query.weight(searcher).scorer(reader); int count = 0; while(s.next()) { count++; } I'm not certain that avoids all scoring work but at least for some of the scorers it should save some CPU time; I'm not sure how much. Also note that the TopDocCollector (used by default if you don't provide your own collector) does not count docs that have score <= 0.0, so the above code fragment would overcount in such cases.
