Hi, yes this is a bug: https://issues.apache.org/jira/browse/LUCENE-2756 There are fixes to this in unreleased code, but in the meantime you can use one of these workarounds: 1. queryParser.setMultiTermRewriteMethod(MultiTermQuery.CONSTANT_SCORE_FILTER_REWRITE) 2. using IndexSearcher over MultiReader instead of MultiSearcher. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
