我尝试过：

GET thing/_search
{
  "query": {
    "bool": {
      "must": {
        "match_all": {}
      },
      "filter": {
        "geo_bounding_box": {
          "location": {
            "top_left": {
              "lat": 47.7328,
              "lon": -122.448
            },
            "bottom_right": {
              "lat": 47.468,
              "lon": -122.0924
            }
          }
        }
      }
    }
  }
}

...但得到以下错误：

"failed_shards" : [
  {
    "shard" : 0,
    "index" : "geofence",
    "node" : "rLGHWGhqRTqDxDlhjA3hhA",
    "reason" : {
      "type" : "query_shard_exception",
      "reason" : "failed to find geo_point field [location]",
      "index" : "geofence",
      "index_uuid" : "sBbXbANQROeQ15IzmBRf3g"
    }
  }
]

......因此，我补充说：

PUT /thing/_mapping
{
  "mappings": {
    "properties": {
      "point": {
        "type": "geo_point"
      }
    }
  }
}

...返回以下错误：

"type" : "mapper_parsing_exception",
"reason" : "Root mapping definition has unsupported parameters:  [mappings : {properties={point={type=geo_point}}}]"

此查询适用于：

GET geofence/_search
{
  "query": {
    "geo_shape": {
      "geometry": {
        "shape": {
          "type": "envelope",
          "coordinates": [ [ -90.0, 90.0], [ 90.0, -90.0] ]
        },
        "relation": "WITHIN"
      }
    }
  }
}

...但这不是边界框，对于-90.0以外的任何值（如-122.0）都将失败
给定以下几何形状：

"geometry" : {
        "type" : "Polygon",
        "coordinates" : [
          [
            [
              -122.661806,

查询边界框内多边形列表的正确方法是什么？

错误状态
找不到geo_point字段[位置]
因此，您需要在Map中添加geo_point类型的location字段，如下所示：

PUT /thing/_mapping
{
    "properties": {
      "location": {
        "type": "geo_point"
      }
  }
}

然后你的第一个查询就可以工作了，只要你确保把数据索引到新的location字段中，但是你的第一个查询只会在给定的边界框内找到“点”。
如果要查找边界框内的面，则需要在geo_shape字段上使用geo_shape query

                    [-50, 75],

                },
              "relation": "within"
              }
            }
          }
        ]
      }
    }
  }

这给出了一个实际的基于坐标的查找与bbox（或任何信封实际上是）...
