A core is a Solr-controlled Lucene index.
A shard is a core that one part of a distributed search. Shards:
SHOULD have the same schema; you will be so sorry if you don't follow this
MUST have the same unique id field,
MUST be disjoint: no document can be in two different shards

How are you querying the core to begin with?

Hi all,
I've been bashing my head against the wall for a few hours now, trying to get
mlt (more-like-this) queries working across multiple cores. I've since seen a
JIRA issue and documentation
Hi Grant,
Thanks for your reply. I'm using solrj to connect via http, which
eventually sends this query

FYI: some people may be confused because of terminoligy -- i think what
you are asking is how to know which *shard* a document came from when
doing a distributed search.
This isn't currently supported, there is an open issue tracking it...
Oops! Sorry, I thought shard and core were one in the same and the
terms could be used interchangeably - I've got a multicore setup which
I'm able to search across by using the shards parameter. I think
you're right, that *is* the question I was asking.
Thanks for letting me know it's not
