The easiest way using the default document routing in solr cloud (which is compositeId hashing), is to just use the same prefix on the ID field for all related documents. This will route them all to the same shard. for example, the following unique IDs will all be routed to the same shard: user15!doc1 user15!whatever user15!yeah http://searchhub.org/2013/06/13/solr-cloud-document-routing/ Or you can use custom sharding and directly assign documents to shards... but if the default compositeId solution works for you, use that. -Yonik http://lucidworks.com
