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](https://www.elastic.co/guide/en/elasticsearch/plugins/current/delete-by-query-usage.html) where you use the ["has parent"](https://www.elastic.co/guide/en/elasticsearch/guide/current/has-parent.html) query.
