HitCollector is the wrong tool to use because you're clearly not interested in collecting hits. Try the Scorer class. For example
Lucene.Net.Search.Weight weight = query.Weight(searcher); Lucene.Net.Search.Scorer scorer = weight.Scorer(searcher.GetIndexReader()); bool hasHits = scorer.Next(); -----Original Message----- From: Artem Chereisky [mailto:[email protected]] Sent: Wednesday, January 13, 2010 6:16 PM To: [email protected]; [email protected] Subject: at least one doc Hi, Given a boolean query and/or a filter, what is the best way to see if there is at least one matching document? I tried a simple hit collector which sets a flag on the first Collect method. Ideally I would want to stop collecting at that point but I couldn't find a way of doing that. I also tried: TopDocs docs = _searcher.Search(query, filter, 1), but it seems to iterate through all matches as docs.totalHits is set the the actual number of matches. So, is there a better way Regards, Art
