SolrCloud works very differently than the old master-slave replication. The index is NOT copied from the leader to the other replicas, except in extreme recovery circumstances. Each replica builds its own copy of the index independently from the others. Due to slight timing differences in the indexing operations, and possible actions related to transaction log replay on node restart, each replica may end up with a different index layout. There also could be differences in the number of deleted documents. Unless something goes really wrong, all replicas should contain the same live documents. Thanks, Shawn
