David Smiley commented on SOLR-10428:

I improved this sort of stuff significantly in SOLR-11444. "collection" can
indeed be a list and potentially include aliases. Even
{{/solr/colA,colB/select?...}} works (as of SOLR-11444). This isn't documented
sufficiently, unfortunately. The SolrJ API could be improved here; should be a
new issue. Since it's so rare to specify more than one collection/alias, it
just says "collection". It's kinda a trick that it can be a list.
[~phpock] can you please try a more recent Solr version, 7.2.0 or beyond, and
see if the problem persists?

Shawn Heisey commented on SOLR-10428:
-
The collection parameter that is mentioned on the wiki page you linked is a URL
parameter. To use that kind of syntax with SolrJ, you would use this code:
{code:java}
params.set("collection","alias-a,alias-b");
solrClient.query(params, SolrRequest.METHOD.POST)
{code}
The way your code supplies the collection parameter on the works differently.
I think that SolrJ puts the provided collection into the URL path -- if you use
, SolrJ sends to http://host:port/solr/ as the base URL. I have not
verified 100% that this is the case, but I think that is how it works.

Philip Pock commented on SOLR-10428:
Sorry for the late reply. The only mention I could find about providing
multiple collections in the parameter is from
[https://wiki.apache.org/solr/SolrCloud#Distributed_Requests]
{quote}Query all shards of multiple compatible collections, explicitly
specified:
http://localhost:8983/solr/collection1/select?collection=collection1_NY,collection1_NJ,collection1_CT
{quote}
I also think that "collection" should be changed to "collectionName".

Shawn Heisey commented on SOLR-10428:

The javadoc for the query method you are talking about doesn't say
"collections". It says "collection".
http://lucene.apache.org/solr/6_5_1/solr-solrj/org/apache/solr/client/solrj/SolrClient.html#query-java.lang.String-org.apache.solr.common.params.SolrParams-org.apache.solr.client.solrj.SolrRequest.METHOD-
I've never heard any mention of being able to use a comma-separated list of
collections in that parameter, but the presence of that getCollectionNames
method suggests that my knowledge may have some holes. If the intent really is
to allow a list of collections, perhaps the javadoc on SolrClient needs a
little work. I wonder if a comma-separated list of cores would work with
HttpSolrClient.
One thing that I know you CAN do with SolrCloud is create an alias on the
server side that queries multiple collections in the cloud, and then only
include that one alias in your query call.
I think I do see a bug in getCollectionNames. In the master branch (as of
right now), line 1409 says this:
{code}
String alias = stateProvider.getAlias(collection);
{code}
I believe that "collection" should be changed to "collectionName" in that line,
and that this completely explains the behavior you're seeing. This code was
added by the commit that you've referenced.
