Hi, I've tried to use grouping query on DisMaxRequestHandler without success. When I sent grouping query in Solr Admin, I could see parens of query escaped in 'querystring' line with debugQuery On. Is this the cause of the failure?
e.g. When I send query like +(lucene solr), I can see following line in the result page. <str name="querystring">+\(lucene solr\)</str> When I tried this with StandardRequestHandler, parens of the query were not escaped. And the query was successfully answered. Digging into the source of Solr, I could find the following line at DisMaxRequestHandler.java. userQuery = U.partialEscape(U.stripUnbalancedQuotes(userQuery)).toString(); And partialEscape function seems to carry out the escaping. So... Can I carry out grouping query on DisMaxRequestHandler? If so, should I use special character for grouping in stead of parens? I'm pretty new on Solr. Any reply will help. Thanks in advance.
