q={!join from=id to=id fromIndex=B}id:*

What is the query that you used to do the Join?

There is the Streaming expression which has the various Join function, but
it requires Solr version 6 onward.

Solr Join Failures

[Ray Niu]

Hi:
   We encounter an issue when using join query in Solr Cloud, our version
is 5.5.2. We will query collection A and join with Collection B in the
runtime, collection A and B always co-exist in the same node.
   Sometimes we found collection B was down for some reason, while
collection A was still active, during that period if we issue join query,
we will see following errors:
 SolrCloud join: B has a local replica (B_shard1_replica1) on
solrCloud_node1:8080_solr, but it is down
  Can anyone provide any suggestions on such scenario?
