Hi, You CAN join across collections with runtime "join". The only limitation is that FROM collection should not be sharded and joined data should reside on one node. Solr cannot join across nodes (distributed search is not supported). Though using streaming expressions it's possible to do various things... -- Vadim

Hi all,<signaturebeforequotedtext></signaturebeforequotedtext><signatureafterqu otedtext></signatureafterquotedtext> Sorry if the question was already covered. We are using joins across documents with the limitation of having the documents to be joined sitting on the same shard. Is there a way around this limitation and even join across collections? Are there plans to support this out of the box? Thanks! Eric Briere.
