Jack Krupansky commented on SOLR-8812: -------------------------------------- The difference in the generated query appears to be the "))~2" which indicates a BooleanQuery with a minShouldMatch of 2 which means that both OR/SHOULD terms MUST match, effectively turning SHOULD/OR into MUST/AND. I'm guessing it was this 5.5 change: SOLR-2649: {code} * SOLR-2649: MM ignored in edismax queries with operators. (Greg Pendlebury, Jan Høydahl et. al. via Erick Erickson) {code} I think q.op=AND simply sets MM=100%, effectively overriding the explicit OR. > ExtendedDismaxQParser (edismax) ignores Boolean OR when q.op=AND > ---------------------------------------------------------------- > > Key: SOLR-8812 > URL: https://issues.apache.org/jira/browse/SOLR-8812 > Project: Solr > Issue Type: Bug > Components: query parsers > Affects Versions: 5.5 > Reporter: Ryan Steinberg > > The edismax parser ignores Boolean OR in queries when q.op=AND.
