Expand _source includes to support nested fields.

Filtering on fields only match the root field, not any nested results.

Would be great to be able to either recursively filter fields or specify the full paths to the nested fields.

Example:

"_source": {  
"data": {  
"id": "211bcebc-2a8f-4a58-9560-198cb10be2e7",  
"name": "One time ",  
"classification": "Product Addon",  
.....  

A lookup for a nested field could logically be:

"_source": {  
        "includes": [  
                "data.name",  
                "data.classification"  
        ]  
}  

To return only the name and classification fields in the results.

Any update on this feature, we have quite large documents and this would save huge amounts of network traffic.
