> It is necessary to co-locate replicas of different collection together in a node when cross-collection joins are performed.
> while creating a collection specify the parameter {{withCollection=other-collection-name}} . This ensure that Solr always ensure that atleast one replica of {{other-cllection}} is present with this collection replicas
> This requires changing create collection, create shard and add replica APIs as well because we want a replica of collection A to be created first before a replica of collection B is created so that join queries etc are always possible.
