> If you specify group=true but don't specify group.query or group.field SOLR throws a SEVERE exception following which we see the empty queries and finally no responses via solrj and admin console gives numFound always equal to total number of docs in index (it's 21692 as shown below). Looks like the searcher goes for a spin once it encounters the exception. Such situation should have been gracefully handled
