             Summary: Shard Split doesn't work on indexes that have nested documents
                 Key: SOLR-11191
                 URL: https://issues.apache.org/jira/browse/SOLR-11191
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: Varun Thacker


The split shard command doesn't split a shard correctly when the index has parent-child documents.

The way split shard works is it goes through all documents id's in that shard and then decides which sub-shard would it belong in . It is not aware of the parent child relationship during this process

So the parent-child documents could be orphaned and end up in different shard
Secondly, even with the routing of parent and child documents were the same split shards needs to re-index them as a block
