Find all parents by parent and child search

I'm new to Elasticserch and I'm looking for a way to find all parents base on a query but also bring up parents based on their children.

Parent records
    ID      Text       
    1        bob        
    2        john       
    3        bobby    

Child Records
    ID     ParentID     Text            
    11    1                   phone        
    22    2                  bob             
    33    3                   green

I want to search "bob" and find all 3 parent records.
Parent ID 2 will come up in results based on Child 22 Text "bob"

Is this possible?

So you want to find both parent and children with bob in them?
