ES6.2.1中query_string不支持fileds了吗?

{

    "query":{

      "query_string":{

          "query":"入门",

          "fileds":["title","author"]

      }

    }

}

send之后报错：

{

  "error": {

    "root_cause": [

      {

        "type": "parsing_exception",

        "reason": "[query_string] query does not support [fileds]",

        "line": 5,

        "col": 20

      }

    ],

    "type": "parsing_exception",

    "reason": "[query_string] query does not support [fileds]",

    "line": 5,

    "col": 20

  },

  "status": 400

}
