Hi,  
I'm very new to Elasticsearch and I'm trying a simple test like this:

```
    TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
            .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

    JsonObject event = Json.createObjectBuilder().add("d", 44).build();

    IndexResponse response = client.prepareIndex("myindex", "mytype").setSource(event).get();

```

I'm expecting the field "d" to be recognized as integer or long but it enters as text:

```
{
"myindex": {
"aliases": {},
"mappings": {
"mytype": {
"properties": {
"d": {
**"type": "text",**"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
}
},
"settings": {
"index": {
"creation_date": "1485890042953",
"number_of_shards": "5",
"number_of_replicas": "1",
"uuid": "vZpTJhDfREC7viQvESQFKQ",
"version": {
"created": "5000099"
},
"provided_name": "myindex"
}
}
}
}

```

if I'm adding the same object from the command line using curl it does enter as long. So what is the problem with this simple code?

Thanks

I'm not familiar with `JsonObject`. Could you post the source that it generates? I'm not sure which override of `setSource` you are getting. There is an `Object...` override but I don't think it'd do the right thing for `JsonObject`.

JsonObject is javax.json.JsonObject.

The source that is generated is

{"d":44}

It looks like I'm getting to a writer that's not recognized and then the default is to make it a string.  
I'm thinking to write a method to "unwrap" the json and return it to the actual type but is this really necessary?
