我正在使用NEST查询ELasticsearch数据库，以获取在Leaflet地图上的UI上绘制的某些GeoShape中的数据。 我用于执行此查询的服务器端代码如下：
注意： geoJsonFeature 是GeoJson从UI发送到服务器的功能。它是下面代码中所示的 Feature 类类型。
public class Feature
{
public string type { get; set; }
public Properties properties { get; set; }
public Geometry geometry { get; set; }
}
var geometry = geoJsonFeature.geometry;
var type = geometry.type;
var coords = geometry.coordinates[0].Select(shapeArr =>
{
double lon = shapeArr[0];
double lat = shapeArr[1];
return new GeoCoordinate(lat, lon);
});
var polygon = new PolygonGeoShape(
new[]
{
coords
});
var result = dbClient.Search<MediaSummary>(s => s
.Index("mediasummary")
.Type(typeof(MediaSummary))
.Query(q =>
q.GeoShapePolygon(c => c
.Name("geoShape_query")
.Boost(1.1)
.Field(p => p.location)
.Coordinates(polygon.Coordinates)
.Relation(GeoShapeRelation.Intersects)
.IgnoreUnmapped(true)
)));
var count = result.Total;
var list= result.Documents.ToList();
无论我在地图上绘制多大的多边形，列表始终为空。 我猜我的服务器端逻辑有问题。
有人可以指导需要做什么吗？
更新：有人请求索引映射和DebugInformation。这些是

# Response:
{"error":{"root_cause":[{"type":"query_shard_exception","reason":"Field [location] is not of type [geo_shape] but of type [geo_point]","index_uuid":"lwHHKK89RzuGn_LZ6DW4Nw","index":"mediasummary"}
注意：“位置”字段的代码中存在区分大小写的问题，即POCO类的名称类似于“位置”而不是“位置”。我已修复此问题，现在在其映射和DebugInformation上方进行介绍。
现在清楚地表明该错误是由于以下原因：
Field [location] is not of type [geo_shape] but of type [geo_point]"
但是我现在不明白下一步该怎么做？
