Hi,  
I am using Elasticsearch/logstash and have an issue when updating an existing index through logstash

imagine the \_source object the first time is:

```
    "_source": {
            "id": "1234",
            "msg_receive_ts": "2017-07-07T14:08:50.115Z",
            "event_status": "SUCCESS",
            "code": "ABCD"
        },

```

Then another row/object comes in on that same document id (1234)

```
    "_source": {
            "id": "1234",
            "msg_receive_ts": "2017-07-07T16:08:50.115Z",
            "event_status": "FAILED"
        },

```

It seems like the whole object is getting replaced. Before I had a 'code' field but now it's gone with this update/upsert through logstash to elasticsearch.

What I want to happen is only the fields that are in the new object get replaced and the other old ones stay.  
So what I would like to see is:

```
    "_source": {
            "id": "1234",
            "msg_receive_ts": "2017-07-07T16:08:50.115Z",
            "event_status": "FAILED",
            "code": "ABCD"
        },

```

Is this easily achievable? Please help.

My output is something like:

```
  output {
       elasticsearch{
           hosts=> ["x.x.x.x:9200"]
           index => "test"
           document_id => "%{id}"
       }
  }
```
