Is there any way that we can implement the below mappings/scenario in elasticsearch 6?  
A {id}  
B (Child of A){id, parentid}  
C (Child of B){id, parentid}  
D(Child of A){id, parentid}

Since types are deprecated from version 6. Do we need to create all the above four as indices?  
How can we query A to get all documents (including its children & grandchildren) with id=xxx
