I am working on a network streaming application and also works as a thin proxy server on top of elasticsearch. The application basically does is query on the ES cluster and then streams the response to a client application.

```
            XContentBuilder xContentBuilder = XContentFactory.jsonBuilder();
            xContentBuilder.startObject();
            response.toXContent(xContentBuilder, ToXContent.EMPTY_PARAMS);
            xContentBuilder.endObject();

```

bytes[] responseStreamBytes = xContentBuilder.bytes().toBytes();

The client side application should do is get the stream and convert the bytes array stream to SearchResponse again.  
How can this be done ?

i have done is use yse readFrom from SearchResponse class. However, it gives a error like

java.io.IOException: Can't read unknown type [121]  
at org.elasticsearch.common.io.stream.StreamInput.readGenericValue(StreamInput.java:433)
