Ravi Kiran Bhaskar created SOLR-4743:
----------------------------------------
Summary: Group query crashes server
Key: SOLR-4743
URL: https://issues.apache.org/jira/browse/SOLR-4743
Project: Solr
Issue Type: Bug
Components: search
Affects Versions: 3.6.2
Environment: CentOS release 5.9, Sun GlassFish Enterprise Server
v2.1.1 Patch15
Reporter: Ravi Kiran Bhaskar
Priority: Critical
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
