如何在 NEST for Elasticsearch 中按 _geo_distance 排序？

Question

是否可以使用 Elasticsearch 的 BEST 库按 _geo_distance 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());

Answer 2

var search2 = _client.Search < Person > (s => s
  .Sort(s => s
    .GeoDistance(g => g
      .Field("location1")
      .Order(SortOrder.Ascending)
      .DistanceType(GeoDistanceType.Plane)
      .Points(search1.Geocoord)
    )
  )
)
