我导入了全国 省和地级市的数据
 pinyin全拼搜索建议 
 

GET /address/_search

{

  "suggest": {

    "mysuggest": {

      "text":"guangdongdd",

    

      "term":{

        "field":"address.spy"

      }

      

    }

  }

}

结果如下：pinyin可以建议 guangdong
 

{

  "took" : 3,

  "timed_out" : false,

  "_shards" : {

    "total" : 1,

    "successful" : 1,

    "skipped" : 0,

    "failed" : 0

  },

  "hits" : {

    "total" : {

      "value" : 0,

      "relation" : "eq"

    },

    "max_score" : null,

    "hits" : [ ]

  },

  "suggest" : {

    "mysuggest" : [

      {

        "text" : "guangdongdd",

        "offset" : 0,

        "length" : 11,

        "options" : [

          {

            "text" : "guangdong",

            "score" : 0.7777778,

            "freq" : 2

          }

        ]

      }

    ]

  }

}

 
使用ik分词器搜索如下
 

GET /address/_search

{

  "suggest": {

    "mysuggest": {

      "text":"广东神",

    

      "term":{

        "field":"address.ik"

      }

      

    }

  }

}

 
结果如下： 使用ik不能搜索出搜索建议
 
 

{

  "took" : 0,

  "timed_out" : false,

  "_shards" : {

    "total" : 1,

    "successful" : 1,

    "skipped" : 0,

    "failed" : 0

  },

  "hits" : {

    "total" : {

      "value" : 0,

      "relation" : "eq"

    },

    "max_score" : null,

    "hits" : [ ]

  },

  "suggest" : {

    "mysuggest" : [

      {

        "text" : "广东",

        "offset" : 0,

        "length" : 2,

        "options" : [ ]

      },

      {

        "text" : "神",

        "offset" : 2,

        "length" : 1,

        "options" : [ ]

      }

    ]

  }

}
