Is _timeStamp a kind of hidden field?

Elastic Stack Elasticsearch

Hi,

Is _timeStamp a kind of hidden field ? Why is this field not displayed in
the result (see hereafter response result) ?

Code

    XContentBuilder mapping = XContentFactory.jsonBuilder()
            .startObject()
              .startObject("time-type")
                .startObject("_timestamp")
                  .field("enabled", true)
                  .field("store", "yes")
                .endObject()
              .endObject()
            .endObject();

    client.admin().indices().prepareCreate("timestamp-id")
            .addMapping("time-type", mapping)
            .execute().actionGet();

    client.prepareIndex("timestamp-id", "time-type", "1")
       .setSource("field1", "value1")
       .setTimestamp("2013-01-01T00:00:00")
       .setRefresh(true).execute().actionGet();

    requestBuilder = client.prepareSearch("timestamp-id")

.setQuery(QueryBuilders.rangeQuery("_timestamp").gte("2012-01-01").lte("2014-01-01"));

    response = requestBuilder.execute().actionGet();

Query :

{
"query" : {
"range" : {
"_timestamp" : {
"from" : "2012-01-01",
"to" : "2014-01-01",
"include_lower" : true,
"include_upper" : true
}
}
}
}

Response

Search result 1 : {
"took" : 17,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},

"hits" : [ {
"_index" : "timestamp-id",
"_type" : "time-type",
"_id" : "1",
"_score" : 1.0, "_source" : {"field1":"value1"}
} ]
}
}

By default, you only get back the document's source (if enabled). If you
want a field, including the timestamp field, you must explicitly ask for it.

Hello!

Try specifying the fields property for your query http://www.elasticsearch.org/guide/reference/api/search/fields/

By default it will load the _source field.

Like that

{
"fields" : ["_timestamp"],
"query" : {
...
}
}

?

field1 should be enclosed in quotes, if not the parser expects one of the
few JSON literals.
