I believe that you are running into this bug: https://issues.apache.org/jira/browse/SOLR-2649 It's a very old bug, coming up on three years. The workaround is to not use boolean operators at all, or to use operators EVERYWHERE so that your intent is explicitly described. It is not much of a workaround, but it does work. Thanks, Shawn
