c# - Geo_Point 属性未按预期编制索引

Question

我正在使用 NEST .net 客户端进行 Elastic Search。我有一个带有 Location 属性的 Address 类。

public class Address
{
public string AddressLine1 {get;set;}
public string AddressLine2 {get;set;}
public string City {get;set;}
public string State {get;set;}
public string ZipCode {get;set;}
[ElasticProperty(Type = FieldType.geo_point)]
public GeoLocation Location {get;set;}
}


public class GeoLocation
{
public float Lat {get;set;}
public float Lon {get;set;}
}

我用 ElasticProperty 属性 geo_point 类型修饰了 Location 属性。我能够为这种类型建立索引。但是当我尝试为此获取映射时，

http://localhost:9200/mysite/Address/_mapping

我希望 Location 属性是“geo_point”类型，而不是它显示类似这样的内容。

{
    "Address": {
        "properties": {                
            "location": {
                "properties": {
                    "lat": {
                        "type": "double"
                    },
                    "lon": {
                        "type": "double"
                    }
                }
            }
        }
    }
}

我在这里遗漏了什么吗？

这是一个完整的示例，说明如何使用 Nest 映射 GeoPoint 以及设置其他属性。希望对 future 的人有所帮助。

public class Location
{
    public decimal Lat { get; set; }
    public decimal Lon { get; set; }
}

public class Building : BaseEntity
{
    public IEnumerable<Location> Location { get; set; }
}

public void CreateBuildingMapping()
{
    var nodes = new List<Uri>() { ... };
    var connectionPool = new Elasticsearch.Net.ConnectionPool.SniffingConnectionPool(nodes);
    var connectionSettings = new Nest.ConnectionSettings(connectionPool, "myIndexName");
    var elasticsearchClient = new Nest.ElasticClient(connectionSettings);

    var putMappingDescriptor = new Nest.PutMappingDescriptor<Building>(connectionSettings);
    putMappingDescriptor.DateDetection(false);
    putMappingDescriptor.Dynamic(false);
    putMappingDescriptor.IncludeInAll(true);
    putMappingDescriptor.IgnoreConflicts(false);
    putMappingDescriptor.Index("myIndexName");
    putMappingDescriptor.MapFromAttributes();
    putMappingDescriptor
        .MapFromAttributes()
            .Properties(p =>
                p.GeoPoint(s =>
                    s.Name(n => n.Location).IndexGeoHash().IndexLatLon().GeoHashPrecision(12)
                )
            );
    putMappingDescriptor.NumericDetection(false);

    elasticsearchClient.Map(putMappingDescriptor);
}
