https://issues.apache.org/jira/browse/SOLR-11191 # Description Prior to this, nested documents could get mis-routed during a the SPLITSHARD command. This results in violated integrity with children ending up on different shards than their parents and being loaded by the [child] transformer onto unintended parents. # Solution If the schema `isUsableForChildDocs` then we tell the shard splitter to use _root_ instead, which is populated with the unique field value of the top parent in the nested hierarchy. This ensures that the entire hierarchy gets colocated during the split. # Tests I have added two tests that add nested documents to a shard. I split the shard, and verify the nested relationship integrity is maintained. # Checklist Please review the following and check all that apply: - [x] I have reviewed the guidelines for [How to Contribute](https://github.com/apache/solr/blob/main/CONTRIBUTING.md) and my code conforms to the standards described there to the best of my ability. - [ ] I have created a Jira issue and added the issue ID to my pull request title. - [ ] I have given Solr maintainers [access](https://help.github.com/en/articles/allowing-changes-to-a-pull-request-branch-created-from-a-fork) to contribute to my PR branch.
