Are you absolutely certain that you have set maxBooleanClauses on *EVERY* core in that Solr instance? This value is global, across the entire JVM, and the last core that starts will set the value for all cores. It is not possible to explicitly control the exact starting order of your cores. If the config option is missing from the last core that gets started, then the global setting will be reset back to 1024. I tried to address this once, but the change was vetoed, and by Apache's rules, I wasn't allowed to do it. https://issues.apache.org/jira/browse/SOLR-4586 I hope to try again and make this situation better for Solr. Thanks, Shawn
