    Description

      Context

      It's about {!join} query parser and distributed mode.

      As is

      SOLR-4905 allows to join from single shard collection to many shards collection. 

      Challenge

      •  Support multiple shards on from side as well,
      •  but strictly stick to collocated indices that promise much performance.
