  您需要在查询中添加 fielddata_fields ，如下所示：

  POST /index/_search
  {
    "query": {
      "match_all": {}
    },
    "fielddata_fields": [
      "location.geohash"
    ]
  }
  

  你会得到这样的东西，_2542440_和 fielddata_fields 中的地理位置

  {
    "hits": {
      "total": 1,
      "max_score": 1,
      "hits": [
        {
          "_index": "test",
          "_type": "test",
          "_id": "1",
          "_score": 1,
          "_source": {
            "location": "13.0009316,77.5947316"
          },
          "fields": {
            "location.geohash": [
              "t",
              "td",
              "tdr",
              "tdr1",
              "tdr1v",
              "tdr1vw",
              "tdr1vww",
              "tdr1vwwz",
              "tdr1vwwzb",
              "tdr1vwwzbm"
            ]
          }
        }
      ]
    }
  }
