C# Nest：如何索引地理点数组

Question

您好，我是 elastic 和 nest 的新手。我使用了一个如何索引地理点位置的示例，效果很好，因为我可以在 kibana 地图可视化中看到地理点。

这是我的数据结构：

public class LocationArray
{
    public string ArrayNameArtical { get; set; }
    [ElasticProperty(Type = FieldType.GeoPoint)]
    public IEnumerable<Location> Locations { get; set; }
}
public class Location
{
    public string Name { get; set; }

    [ElasticProperty(Type = FieldType.GeoPoint)]
    public Coordinate Coordinate { get; set; }
}


public class Coordinate
{
    public double Lat { get; set; }
    public double Lon { get; set; }
}

我的索引代码如下：

var response = client.CreateIndex(indexName, s => s
      .AddMapping<Location>(f => f
        .MapFromAttributes() 
        .Properties(p => p
          .GeoPoint(g => g.Name(n => n.Coordinate).IndexGeoHash().IndexLatLon())
        )
      )
    );
    client.IndexMany(new[]{
        new Location
        {
            Name = "Amsterdam",
            Coordinate = new Coordinate { Lat =  52.3740300, Lon = 4.8896900}
        },
        new Location
        {
            Name = "Rotterdam",
            Coordinate = new Coordinate { Lat = 51.9225000, Lon = 4.4791700}
        },
        new Location
        {
            Name = "Utrecht",
            Coordinate = new Coordinate { Lat =  52.0908300,  Lon = 5.1222200}
        },new Location
        {
            Name = "Den Haag",
            Coordinate = new Coordinate { Lat =  52.3740300, Lon = 4.8896900}
        }
    });

现在我想索引 LocationArray class，似乎需要更改我的映射但我不知道该怎么做..无论如何我可以在 kibana 中看到数组数据但是无法通过地图查看。地理点索引数组有问题吗？

好的所以经过几个小时的挖掘找到了映射这个地理点数组的方法.. 希望有一天它能帮助别人 :)

client.Map<LocationArray>(m => m
                        .MapFromAttributes().Properties(p=>p
                            .NestedObject<Location>(no => no
                            .Name(pl => pl.Locations.First())
                            .Dynamic()
                            .Enabled()
                            .IncludeInAll()
                            .IncludeInParent()
                            .IncludeInRoot()
                            .MapFromAttributes()
                            .Path("full")
                            .Properties(pprops => pprops
                                .GeoPoint(ps => ps
                                    .Name(pg => pg.Coordinate)
                                    .IndexGeoHash().IndexLatLon()
                                )
                            )
                        ))
                    );
