I that case DisjunctionMaxQuery is the way to go (it will only count the hit with highest score and not add scores (coord or not coord doesn't matter here). --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
