Kibana: Support for parent and child relations

[pwli]

Current field list in kibana pick up all document types.
Nested aggregates across fields from document types
don't work (returns no result) as appropriate.

However, if there is a parent-child document relationship,
the filters should work using the appropriate has_parent/child
in the query DSL.

You already have the _parent data in mapping, so you can
create a "forest" that have the parent/child types properly
linked. So by walking this large "tree", we should be able
to place the related filter clauses in the appropriate locations for
a query.

Thanks

Any update on parent-child support? Missing this is a crucial for using ElasticSearch fully.

+1. Parent/Child and Nested Documents are critical for more complicated ElasticSearch use cases.

Having this support would enable Kibana to be the UI used in IT Operations with complex relationships that require advanced usage. +1
