Michael Krkoska commented on SOLR-3740: --------------------------------------- I ran into this issue with a simple query like "ID100", which gets rewritten by a WordDelimiterFilter in my config into "(text:ID text:100)". Unfortunately my q.op=AND is not passed on to the underlying query parser, which results in a OR, as that's the default. Adding {code:java} up.setDefaultOperator(QueryParsing.getQueryParserDefaultOperator(req.getSchema(), solrParams.get(QueryParsing.OP))); {code} in line 193 of ExtendedDismaxQParserPlugin fixes the bug for me and seems sensible. Please look into this before 4.0 release, as it seems to be a rather serious bug. > ExtendedDismaxQParser (edismax) does not obey q.op for parenthesized > sub-queries > -------------------------------------------------------------------------------- > > Key: SOLR-3740 > URL: https://issues.apache.org/jira/browse/SOLR-3740 > Project: Solr > Issue Type: Bug > Components: query parsers > Affects Versions: 3.6.1, 4.0-BETA > Reporter: Jack Krupansky > > For a query such as "cat dog (fox bat fish)" with &q.op=AND, the default > query operator is only set to AND for the top-level query, and not for the > parenthesize sub-query. This is not documented behavior and rather surprising. > This happens because edismax only simulates the default operator by forcing > "mm" (minMatch) to 100% for the top-level BooleanQuery alone and never sets > the default query operator when it invokes the classic Lucene Query parser > which in turn is performing parsing and query generation for the > parenthesized sub-query. > One solution is for edismax to always set the default query operator when > calling the classic Lucene query parser, or at least when q.op=AND. -- This message is automatically generated by JIRA.
