C＃nest弹性搜索地理点数组索引未显示在kibana中 [英] C# nest elasticsearch geo point array index not shown in kibana

问题描述

我有以下课程

public class MyLayer
{
    public List<MyLocation> Locations { get; set; }
}
public class MyLocation
{
    public string Name { get; set; }
    public MyCoordinate Coordinate { get; set; }
}

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

此代码用于索引对象

var node = new Uri("http://localhost:9200");
        string indexName = "geopoint-tests2";
        var settings = new ConnectionSettings(
            node,
            defaultIndex: "geopoint-tests2"
        );

        var client = new ElasticClient(settings);

        var rootNodeInfo = client.RootNodeInfo();
        if (!rootNodeInfo.ConnectionStatus.Success)
          throw new ApplicationException("Could not connect to Elasticsearch!",
            rootNodeInfo.ConnectionStatus.OriginalException);


        client.CreateIndex(indexName, s => s
        .AddMapping<MyLocation>(f => f
          .MapFromAttributes() 
          .Properties(p => p
            .GeoPoint(g => g.Name(n => n.Coordinate).IndexLatLon()))));

        var loc = new MyLayer()
        {
            Locations = new List<MyLocation>()
        };
        loc.Locations.AddRange(new []
                        {
                          createLocation("Amsterdam", 52.3740300, 4.8896900),
                          createLocation("Rotterdam", 51.9225000, 4.4791700),
                          createLocation("Utrecht", 52.0908300, 5.1222200),
                          createLocation("Den Haag", 52.0908300, 5.1222200)
                        });

        client.Index(loc);

正如你所知，我想要索引一个位置数组，但由于某种原因我看不到地理位置索引在kibana平铺地图，当我索引平面类型的MyLocation我看到地理索引与地图visualzation。

As you can i want index an array of location but for some reason I can't see the geo index in kibana Tile map, when I indexed flat type of MyLocation i seen the geo index with the map visualzation.

在kibana 4.0我看到位置没有索引 - 但无法确定如何索引...

In kibana 4.0 I see that Location is not indexed - but could not figure how to index it...

问题是与代码有关吗？在kibana中的索引？我的索引位置数组？

Is the problem is with code?Index in kibana?My approch of indexing array of location?

感谢您的时间和帮助：）

Thank you for your time and help :)

推荐答案

我已经取得了成功模型：

I've had success with this model:

internal class Location
{
    [JsonProperty(PropertyName = "lat")]
    public double Latitude { get; set; }

    [JsonProperty(PropertyName = "lon")]
    public double Longitude { get; set; }

}

然后将其映射到：

.MapFromAttributes()
    .Properties(p =>
        p.GeoPoint(s =>
            s.Name(n => n.Location).IndexGeoHash().IndexLatLon().GeoHashPrecision(12)
            )
        )

然后它显示在Kibana

Then it shows up in Kibana
