Hi Erick I downloaded the latest build from ( https://builds.apache.org/job/Solr-3.x/lastSuccessfulBuild/artifact/artifacts/ ) But, I don't find the required class CollapseComponent in the src. (org.apache.solr.handler.component.CollapseComponent).
The SolrJ in 3.4 does seem to have something like GroupResponse, GroupCommand classes, which might be the ones I am looking for (though I am not very sure). Regards Sowmya.
