I have few indices A,B,C each having userId,name,etc.

I want to search text in A and if a hit is found, the payload should return  
the following:

1. userId, name of that doc in Index A
2. documentID/s of Index B,C

This behavior extends to the search in Index B and C as well.

_Step 1. How do I store this in the payload for each Index ?_

_The structure for payload looks like, eg.A_  
_"payload" : {_

- "userId" : "A1",\*  
_"name" : a1",_  
_"documentIDForB" : ,_  
_"listDocumentIDForC" : []_  
_}_

_Step 2. How do I retrieve the payload information directly from Index B,C  
? Is this treated as any other regular field when retrieving info from a  
doc in ES?_

Thanks
