Is there any known issue with using group.ngroups in a distributed Solr using version 4.8.1 ?
I recently upgraded a cluster from 4.6.1 to 4.8.1, and I'm noticing several queries where ngroups will be more than the actual groups returned in the response. For example, ngroups will say 5, but then there will be 3 groups in the response. It is not happening on all queries, only some.
