如何在弹性搜索中基于多个地理点搜索文档？

Question

我有一个用例，我想在其中搜索具有多个地理点的文档。

{
  "query": {
    "bool": {
      "must": {
        "match_all": {}
      },
      "filter": {
        "geo_distance": {
          "distance": "100m",
          "nc_extraData.nc_geoPoint": {
            "lat": 21.36042723377568,
            "lon": -5.646749208228298
          }
        }
      }
    }
  }
} 

此查询仅支持单个地理点。 可能吗。

Answer 1

您可以添加多个具有不同地理点的geo_distance约束。 您还可以使用命名查询知道哪个点匹配：

{
  "query": {
    "bool": {
      "should": [
        {
          "geo_distance": {
            "distance": "100m",
            "nc_extraData.nc_geoPoint": {
              "lat": 21.36042723377568,
              "lon": -5.646749208228298
            },
            "_name": "point 1"
          }
        },
        {
          "geo_distance": {
            "distance": "100m",
            "nc_extraData.nc_geoPoint": {
              "lat": 22.36042723377568,
              "lon": -6.646749208228298
            },
            "_name": "point 2"
          }
        },
        {
          "geo_distance": {
            "distance": "100m",
            "nc_extraData.nc_geoPoint": {
              "lat": 23.36042723377568,
              "lon": -7.646749208228298
            },
            "_name": "point 3"
          }
        }
      ]
    }
  }
}

  "query": {
    "bool": {
      "should": [
        {
          "geo_distance": {
            "distance": "6000km",
            "nc_extraData.nc_geoPoint": {
              "lat": 39.783181787374076,
              "lon": -100.72051270885312
            },
            "_name": "point 1"
          }
        },
        {
          "geo_distance": {
            "distance": "6000km",
            "nc_extraData.nc_geoPoint": {
              "lat": 39.73750007106965,
              "lon": -90.00078544604122
            },
            "_name": "point 2"
          }
        },
         {
          "geo_distance": {
            "distance": "1000m",
            "nc_extraData.nc_geoPoint": {
              "lat": 60.73750007106965,
              "lon": -90.00078544604122
            },
            "_name": "point 3"
          }
        }
      ]
    }
  }
}```

I am trying this query. But the matching query contains both ``` "matched_queries": [
                    "point 2",
                    "point 1"
                ]``
