Hi All, Is there any way to achieve creation of parent child mapping in two different indices. As mentioned in documentation [http://www.elastic.co/guide/en/elasticsearch/guide/master/parent-child-mapping.html](http://www.elastic.co/guide/en/elasticsearch/guide/master/parent-child-mapping.html) The documentation gives examples of same index like company I tried to create two indices Index Type Company Branch Employee Employee I have mentioned parent (branch) mapping in Employee type. There is no error during creation of mapping and building index. But elasticsearch is throwing error while searching using has\_child or has\_parent in queries. Is there any way to maintain two types of parent child relation in two different indices ? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hello Pavan , This is not possible. The parent and child need to be on the same index and same shard. To ensure this such a rule is imposed. Thanks Vineeth Mohan, Elasticsearch consultant, [qbox.io](http://qbox.io) ( Elasticsearch service provider [http://qbox.io/](http://qbox.io/)) On Wed, Apr 8, 2015 at 5:46 AM, Pavan Kumar [pavan.bnv@gmail.com](mailto:pavan.bnv@gmail.com) wrote: > Hi All, > > Is there any way to achieve creation of parent child mapping in two > different indices.
