Jasper van Veghel commented on SOLR-2066:
-----------------------------------------
Apologies for continuing to bring up issues ;-) but it seems that facets also
cause problems with empty result sets. Modify the TestDistributedGrouping test
as follows and you'll see:
{code}// Test distributed grouping with empty indices
query("q", "*:*", "rows", 100, "fl", "id," + i1, "group", "true",
"group.field", i1, "group.limit", 10, "sort", i1 + " asc, id asc");
query("q", "*:*", "rows", 100, "fl", "id," + i1, "group", "true",
"group.field", i1, "group.limit", 10, "sort", i1 + " asc, id asc",
"hl","true","hl.fl",t1);
query("q", "*:*", "rows", 100, "fl", "id," + i1, "group", "true",
"group.field", i1, "group.limit", 10, "sort", i1 + " asc, id asc", "facet",
"true", "facet.field", t1);{code}
