I am using the Java API and get the result of a search:

final GetResponse response =  
\_esClient.prepareGet(\_index, \_type, (String) key)  
.execute().actionGet();

Now, I can get the source as a Map or as a String using:

```
    Map<String, Object> result = response.getSource();
    String result = response.sourceAsString();

```

But, I want to "inject" some additional response properties into my source  
(i.e. \_type, \_version, \_index) which I will return as a String. Getting the  
Map back then injecting the properties is trivial, but there isn't a  
convenient way (that I could find) to convert the map back to a JSON  
string.

Is there a config property to inject these additional fields into source  
already? Or some technique to accomplish what I would like?

XContentFactory.jsonBuilder().map(responseAsMap).string()

Thanks, I'll give that a try.
