Jason Gerlowski commented on SOLR-15347:
----------------------------------------
Hi Nathan,
We reserve JIRA use for verified bugs or improvements. Questions and requests
for help like the one you posted here are better sent to the Solr's "user"
mailing list: us...@solr.apache.org which has more eyes on it day-to-day.
It can be frustrating to not get a response on the users-list, if you've
already asked there. But patience and persistence are really the best
strategies for working around that (instead of cross-posting here). Very few
people read all JIRA tickets exhaustively compared to the number of eyes on the
users list. If it's been some time and this is still relevant, give your
thread a bump and ask again if anyone has any ideas or information about
grouping's limitations.

> I am trying to make a simple group call. This is on a distributed solr
> instance with 6 shards and 60m documents. I can make this same call when I
> was on
> a non distributed index. My understanding is that group still works on a
> distributed index as long as you are not using ngroups, group.func, and
> group.facet.

> I will post some iterations I have tried. I have gotten two different errors
> based on the number of shards. This works with 1 shard so it seems to be with
> distributed searches. I started on 8.6 but then updated to 8.8.1. My solr
