This code:
SolrServer server;
server = new HttpSolrServer("http://server:port/solr/corename";);
((HttpSolrServer) server).setMaxRetries(1);
((HttpSolrServer) server).setConnectionTimeout(5000);
SolrQuery q = new SolrQuery();
q.setRequestHandler("/get");
q.set("id","ai_spa509997");
System.out.println(q);
QueryResponse r = server.query(q);
System.out.println(r);
Produced this output:
qt=%2Fget&id=ai_spa509997
{doc=SolrDocument{location=PARIS,FRANCE,
photographer_id=22213,[lots_redacted]}}

If you set the "collection" parameter on a request to the name of the
collection you want to query/update, that should do what you're after.
You'll need to do all changes with an UpdateRequest object -- the
syntactic sugar methods (add, deleteByQuery, etc) don't handle cases
where you need to set parameters on the request.

Another possibility is to create multiple CloudSolrServer objects and
use 'setDefaultCollection' on each of them, but that seems like complete
overkill unless you've got a small number of collections. If you are
absolutely sure that you won't have multiple threads using the
CloudSolrServer object, you could call setDefaultCollection before each
use ... but IMHO that's sloppy coding.
