I think the api is : http://localhost:8983/solr/admin/collections?action=CREATEALIAS&name=alias&collections=collection1,collection2,...
And you can do query like: http://localhost:8983/solr/alias/select?... And it will query collection1 and collection2. I tried it using solr 4.2.1, it works. Thanks Mark for this great feature but I suggest you can update the wiki too. thanks, Brad -- View this message in context: http://lucene.472066.n3.nabble.com/Does-solr-cloud-support-rename-or-swap-function-for-collection-tp4054193p4054343.html Sent from the Solr - User mailing list archive at Nabble.com.
