Is there something different I need to do for a query with a join for a
Collection? Singular Collection, not across Collections.
Initially, I used a Core for simple development. One of my queries uses a
join. It works fine.
I know very little about using the join feature. Everything that I know
about it has been picked up by reading this mailing list.
I think one of the key elements is that all of the indexes involved in a
join must exist on the same server. It is quite common with a SolrCloud
setup to have the data spread across multiple servers, especially when
collections have multiple shards.
I do not know whether you're having a problem because of having your
collection spread across multiple servers or not, but it does seem to be
a likely possibility.
Thanks,
