I'm assuming from that link I would use the following: /Query all shards of multiple compatible collections, explicitly specified:/ http://localhost:8983/solr/collection1/select?collection=collection1_NY,collection1_NJ,collection1_CT
where collection1_NY, NJ and CT could be books, movies, music in my case. But what does it mean to be a 'compatible' collection? If that just means the schema.xml for each of them has to have a common field or fields that can be searched against, then I'm golden. But if 'compatible' means something more specific I would need a definition to see if this will work for me.
