This comment for the benefit of who is using distributed search: The protocol of communication has been xml for distributed search. For a good part of 1.3. It is now changed to a custom binary format (SOLR-486 ). So each shard participating in a distributed search must be using the same protocol. Safest thing is to install each shard with same binaries. --Noble
