地理距离查询

匹配给定地理点一定距离内的 geo_point 和 geo_shape 值。

示例

假设已索引以下文档

resp = client.indices.create(
    index="my_locations",
    mappings={

使用 geo_distance 过滤器匹配指定地理点一定距离内的 geo_point 值

resp = client.search(
    index="my_locations",
    query={
        "bool": {
            "must": {
                "match_all": {}
            },
            "filter": {
                "geo_distance": {
                    "distance": "200km",
                    "pin.location": {
                        "lat": 40,
                        "lon": -70
                    }
                }
            }
        }
    },

print(resp)

response = client.search(
  index: 'my_locations',
  body: {
    query: {
      bool: {
        must: {
          match_all: {}
        },
        filter: {
          geo_distance: {

            }
          }
        }
      }
    }
  }
)
puts response

const response = await client.search({
  index: "my_locations",
  query: {
    bool: {
      must: {
        match_all: {},
      },
      filter: {
        geo_distance: {
          distance: "200km",
          "pin.location": {
            lat: 40,
            lon: -70,

使用相同的过滤器匹配给定距离内的 geo_shape 值

resp = client.search(
    index="my_geoshapes",
    query={
        "bool": {
            "must": {
                "match_all": {}
            },
            "filter": {
                "geo_distance": {
                    "distance": "200km",
                    "pin.location": {
                        "lat": 40,
                        "lon": -70
                    }
                }
            }
        }
    },
)
print(resp)

response = client.search(
  index: 'my_geoshapes',
  body: {
    query: {
      bool: {
        must: {
          match_all: {}
        },
        filter: {
          geo_distance: {
            distance: '200km',
            'pin.location' => {
              lat: 40,
              lon: -70
            }
          }
        }
      }
    }
  }
)
puts response

const response = await client.search({

  query: {
    bool: {
      must: {
        match_all: {},

要匹配 geo_point 和 geo_shape 值，请搜索这两个索引

resp = client.search(
    index="my_locations,my_geoshapes",
    query={
        "bool": {
            "must": {

            },
            "filter": {
                "geo_distance": {
                    "distance": "200km",
                    "pin.location": {
                        "lat": 40,
                        "lon": -70
                    }
                }
            }
        }
    },
)
print(resp)

response = client.search(
  index: 'my_locations,my_geoshapes',
  body: {
    query: {
      bool: {
        must: {
          match_all: {}
        },
        filter: {
          geo_distance: {

            'pin.location' => {

              lon: -70
            }
          }
        }
      }

puts response

选项

编辑

以下是过滤器允许的选项

`distance`	以指定位置为中心的圆的半径。落入此圆圈内的点被视为匹配。 `distance` 可以使用各种单位指定。请参阅距离单位。
`distance_type`	如何计算距离。可以是 `arc`（默认值）或 `plane`（更快，但在长距离和靠近两极时不准确）。
`_name`	用于标识查询的可选名称字段
`validation_method`	设置为 `IGNORE_MALFORMED` 以接受纬度或经度无效的地理点，设置为 `COERCE` 以另外尝试推断正确的坐标（默认值为 `STRICT`）。

每个文档的多位置

编辑

geo_distance 过滤器可以处理每个文档的多个位置/点。一旦单个位置/点与过滤器匹配，文档将包含在过滤器中。

忽略未映射

编辑

当设置为 true 时，ignore_unmapped 选项将忽略未映射的字段，并且不会为此查询匹配任何文档。这在查询可能具有不同映射的多个索引时非常有用。当设置为 false（默认值）时，如果字段未映射，则查询将抛出异常。
