I try to delete my document using bluk api（es version 5.6.2), the requestis:

POST _bulk

        (
            [0] => Array
                (
                    [delete] => Array
                        (

                            [_index] => logdb_dwc
                            [_type] => pumpOnlineGaming
                            [_id] => 5b6ee6e20e1f39d201e625e8
                            [_version] => 2
                            [result] => deleted
                            [_shards] => Array
                                (
                                    [total] => 2
                                    [successful] => 2
                                    [failed] => 0
                                )
                            [status] => 200
                        )
                )
        )
)

GET /logdb_dwc/pumpOnlineGaming/5b6ee6e20e1f39d201e625e8
{
  "_index": "logdb_dwc",
  "_type": "pumpOnlineGaming",
  "_id": "5b6ee6e20e1f39d201e625e8",
  "_version": 3,
  "found": true,
  "_source": {
    "playerId": 13982512,
    "_create_time": "2018-08-11T13:38:42+00:00"
