I have an index name "relations" which has the following types: relation, person, car  
the relation is the parent, and each relation has 2 children: person & person, car & car, person & car  
person and car both has a field "ref\_id"

now, the user is giving me an input of list of ref\_ids, and i need to bring all the relations that has those id in both of the children.  
my query will be should clause with "has\_child" on type person and another "has\_child" on type car with min\_children:2  
the problem will be in the person-car relation - how i can make a child query with min\_children on 2 different types?
