如何在 NEST for Elasticsearch 中按 _geo_distance 排序？

Question

是否可以_geo_distance使用用于弹性搜索的 NEST 库进行排序？我找不到任何支持。

做我想做的原始json是：

"sort": [
      {
         "_geo_distance": {
            "position": {
               "lat": 59.3389428,
               "lon": 18.0761637
            },
            "order": "asc",
            "unit": "m",
            "distance_type": "plane"
         }
      }
   ]

Answer 1

var results = client.Search<object>(sd => sd
    .SortGeoDistance(d => d
        .OnField("position")
        .Unit(GeoUnit.Miles)
        .DistanceType(GeoDistance.Plane)
        .PinTo(Lat: 59.3389428, Lon: 18.0761637)
        .Ascending());
