Getting parent id in parent-child mapping

Elastic Stack Elasticsearch
1

I am using parent-child and the mapping is having the field _parent and I
set parent to actual parent id during indexing.
But the search result returns all the fields except the parent and I also
could not figure out any method to get the parent id.
How should I get a parent id of the child document ?

Thanks

Hi Chetana,

You can specify the _parent and _source in the fields. It will list the
_parent in the "fields" array in the hit, but the _source will be at it's
normal place in the hit.

curl 'localhost:9200/indexname/childname/_search' -d '{
fields:["_parent", "_source"]
}'
