May be consider having one collection with implicit sharding ? This way you can have all advantages of solrcloud and can control content of each core "manualy" as well as query them independently (&distrib=false) ... or some of them using &shards=core1,core2 as was proposed before Quote from doc " If you created the collection and defined the "implicit" router at the time of creation, you can additionally define a router.field parameter to use a field from each document to identify a shard where the document belongs. If the field specified is missing in the document, however, the document will be rejected. You could also use the _route_ parameter to name a specific shard." -- Vadim
