I want to extend the json response with some custom logic data, from  
business specific needs. Is there a plugin mechanism or something I  
can do this.

For exampe to add in the response:  
{  
userdata:{  
"prop1":"aaaa",  
"prop2":"bbbb",  
}  
hits:{  
...........................  
}  
}

No, you need to proxy the call to elasticsearch yourself, and add what you want. Where do you get that data from?

Hi kimchy,  
thanks for the answer.

I agreee it is a better idea to proxy it, es doesn' need to care about this.  
I was just curious whether it' possible to write such custom plugin, I see  
you use plugins for some functionality.

The data we want to extend the response with at the moment comes from a  
database, we are also thinking over the possibility to put it in a different  
type in the es.

There isn't an extension point for that. And, things like that shouldn't probably exist in elasticsearch.
