Delete Child Documents using parent Id in Parent Child

Elastic Stack Elasticsearch

I have created the parent child mapping for vpost and vplike
Added data as follows
POST /ab/vpost/_bulk
{"index":{"_id": 1}} {"title":"Olympic post 1","uId":"101","uName":"suyog"]}
{"index":{"_id": 2}} {"title":"rio2016 post 1","uId":"101","uName":"suyog"}
POST /ab/vplike/_bulk
{"index":{"_id": 102, "parent": 1}} {"uId":"102","uName":"prasad"}
{"index":{"_id": 103, "parent": 1}} {"uId":"103","uName":"abhijit"}
{"index":{"_id": 101, "parent": 2}} {"uId":"101","uName":"suyog"}
{"index":{"_id": 103, "parent": 2}} {"uId":"103","uName":"abhijit"}
{"index":{"_id": 102, "parent": 2}} {"uId":"102","uName":"prasad"}

I have parent Id of "vpost" and want to delete the all "vplike" for parent.
What will be the best approach? Please suggest. Thanks in advance.

Delete by query where you use the "has parent" query.
