@Chris I have solrcloud 4.4 running with 3 shards and 2 cores. A cross-core
join does not work even when cores are created during the bootstrap time.
This is my query:
{noformat} http://SOLR_SERVER/solr/merchant/select?q={!join from=merchantId
to=merchantId fromIndex=deals}apple {noformat}
This query returns no documents, full response with debugQuery=true:
http://apaste.info/uHOw
But both of my cores have a common merchantId when I query for "apple". So I
think this problem is a general problem in solrcloud.

>
> Using a non-SolrCloud setup, it is possible to perform cross core joins
> (http://wiki.apache.org/solr/Join). When testing with SolrCloud, however,
> neither the collection name, alias name (we have created aliases to SolrCloud
> collections), or the automatically generated core name (i.e.
> <collection>_shard1_replica1) work as the fromIndex parameter for a
> cross-core join.
