尝试在一个 ElasticSearch 的 index 中导入多个 type 时报错，报错信息如下：

```bash
[responseCode] => 400
    [responseHeaders] => Array
        (
            [content-type] => application/json; charset=UTF-8
            [content-length] => 355
        )

    [responseBody] => Array
        (
            [error] => Array
                (
                    [root_cause] => Array
                        (
                            [0] => Array
                                (
                                    [type] => illegal_argument_exception
                                    [reason] => Rejecting mapping update to [shiqidu] as the final mapping would have more than 1 type: [discussion, article]
                                )

                        )

                    [type] => illegal_argument_exception
                    [reason] => Rejecting mapping update to [shiqidu] as the final mapping would have more than 1 type: [discussion, article]
                )

            [status] => 400
        )

```

原因：6.0的版本不允许一个 index 下面有多个 type，并且官方说是在接下来的7.0版本中会删掉 type ，[官方说明](https://www.elastic.co/guide/en/elasticsearch/reference/6.0/removal-of-types.html#removal-of-types) ，搞得有点迷，看一些文章说 ElasticSearch 的 `index` 相当于 `数据库`，`type` 相当于 `数据表`，但是现在看来，如果要储存多个表的数据，还是得建立多个 index 索引。
