Returning the type of the suggester

　　有时你需要知道确切的suggester类型，以解析其结果。 typed_keys参数可用于在响应中更改suggester的名称，它将以其类型为前缀。

　　考虑以下两个suggester term 和phrase的例子：

POST _search?typed_keys
{
  "suggest": {
    "text" : "some test mssage",
    "my-first-suggester" : {
      "term" : {
        "field" : "message"
      }
    },
    "my-second-suggester" : {
      "phrase" : {
        "field" : "message"
      }
    }
  }
}

　　在回应中，suggester命名将分别改为term＃my-first-suggester和phrase＃my-second-suggester，以反映每个suggestion的类型：

{
  "suggest": {
    "term#my-first-suggester": [ 【1】
      {
        "text": "some",
        "offset": 0,
        "length": 4,
        "options": []
      },
      {
        "text": "test",
        "offset": 5,
        "length": 4,
        "options": []
      },
      {
        "text": "mssage",
        "offset": 10,
        "length": 6,
        "options": [
          {
            "text": "message",
            "score": 0.8333333,
            "freq": 4
          }
        ]
      }
    ],
    "phrase#my-second-suggester": [ 【2】
      {
        "text": "some test mssage",
        "offset": 0,
        "length": 16,
        "options": [
          {
            "text": "some test message",
            "score": 0.030227963
          }
        ]
      }
    ]
  },
  ...
}

　　【1】名字my-first-suggester现在包含term前缀。　

　　【2】名字my-second-suggester现在包含phrase前缀。
