Jasper van Veghel commented on SOLR-2066:
-----------------------------------------
Great - ngroups is coming through now! Another thing I noticed is that
highlighting doesn't work on account of the resultIds not getting set in the
ResponseBuilder. It only happens in combination with _distributed_ grouping -
so it works when I do this:
http://localhost:8983/solr/foo/select?wt=json&rows=2&group=true&group.field=dcterms_source&group.ngroups=true&hl=true
Or this:
http://localhost:8983/solr/foo/select?wt=json&rows=2&shards=localhost:8983/solr/foo,localhost:8983/solr/bar&hl=true
But not this:
http://localhost:8983/solr/foo/select?wt=json&rows=2&group=true&group.field=dcterms_source&group.ngroups=true&shards=localhost:8983/solr/foo,localhost:8983/solr/bar&hl=true
