Group count in SOLR 3.3

Wed, 22 Aug 2012 23:24:42 -0700 

Hi guys,
we are using SOLR 3.3 with Solrj inside our java project. In actual version we had to add some grouping support, so we add parameters into SolrQuery object like this: 

        query.setParam(GroupParams.GROUP, true);
        query.setParam(GroupParams.GROUP_MAIN, true);
        query.setParam(GroupParams.GROUP_FIELD, OUR_GROUP_FIELD);

and we get QueryResponse with results we need. Awesome!


But now I have one remaining problem, I don't know how get number of 
groups from QueryResponse. I found I must add group.ngroups=true param 
into query. So I did it:


       query.setParam(GroupParams.GROUP_TOTAL_COUNT, true);


But QueryResponse seems same. There's no method like "getGroupCount()" 
or group count param in header.



Am I doing something wrong? Or is it SOLR 3.3 problem? If we upgrade to 
newer version, will it works?


Thanks for any advice!

Roman
