      "term": {
        "suggest_mode": "always",
        "min_word_length":10,

    },

}

结果是：

  "timed_out": false,

    "total": 5,
    "successful": 5,
    "skipped": 0,

            "score": 0.5,

在term query中，需要的是：not analyzed。即是字段是 keyword类型的，不进行分词处理的字段。

在term suggester中，如何对中文进行处理？说明：上述是安装了ik分词的。
