不确定您的longitude字段的数据类型，因为geo-point data type不支持范围查询，如果您使用正常的整数，它将工作，如下所示。

使用默认整数Map为示例文档编制索引

put my-idx-number-range/_doc/4
{
  "longitutde" : -10
}
put my-idx-number-range/_doc/4
{
  "longitutde" : 20
}
put my-idx-number-range/_doc/4
{
  "longitutde" : 10
}
put my-idx-number-range/_doc/4
{
  "longitutde" : 50
}

带范围的搜索查询

POST my-idx-number-range/_search
{
  "query": {
    "bool": {
      "filter": [
        {
          "range": {
            "longitutde": {
              "gte": -73,
              "lte": 20
            }
          }
        }
      ]
    }
  }
}

和搜索结果

"hits" : [
      {
        "_index" : "my-idx-number-range",
        "_type" : "_doc",
        "_id" : "1",
        "_score" : 0.0,
        "_source" : {
          "longitutde" : -20
        }
      },
      {
        "_index" : "my-idx-number-range",
        "_type" : "_doc",
        "_id" : "2",
        "_score" : 0.0,
        "_source" : {
          "longitutde" : 20
        }
      },
      {
        "_index" : "my-idx-number-range",
        "_type" : "_doc",
        "_id" : "3",
        "_score" : 0.0,
        "_source" : {
          "longitutde" : 10
        }
      }
    ]
