Re: Group count in SOLR 3.3

Thanks, I found GroupResponse was added in Solr 3.4 so I have to update 
version :)

3.6 has a getNGroups, does that do what you want?

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!
