我在 C# 中使用 NEST（版本 7.7.1）创建动态索引。数据包含需要在弹性搜索（elastic.co 上的 7.6.1 版）索引中存储为 geo_point 的地理位置。但是映射没有发生。它总是将它作为对象而不是 geo_point。
我尝试了多种选择，例如 1) 自动映射 2) 手动映射 3) 使用手动映射进行自动映射。
以下是代码
Uri EsInstance = new Uri(EsUrl);
ConnectionSettings EsConfiguration = new ConnectionSettings(EsInstance);
if (!string.IsNullOrWhiteSpace(EsUser))
EsConfiguration.BasicAuthentication(EsUser, EsPass);
EsClient = new ElasticClient(EsConfiguration);
var settings = new IndexSettings { NumberOfReplicas = 2, NumberOfShards = 5 };
indexConfig = new IndexState
{
Settings = settings
};
var res = await EsClient.CreateIndex(indexName,
c => c.Index(indexName)
.Map<TripInsightDocument>(
m => m.Properties(ps => ps)
.AutoMap()
.Properties(ps => ps
.Object<TripInsightLeg>(o => o
.Name(n => n.legs)
.AutoMap()
.Properties(lp => lp
.GeoPoint(gp => gp.Name(fn => fn.fpos).IgnoreMalformed(true))
.GeoPoint(gp => gp.Name(fn => fn.tpos).IgnoreMalformed(true))
)
)
.Object<TripInsightStop>(o => o
.Name(n => n.stops)
//.AutoMap()
.Properties(lp => lp
.GeoPoint(gp => gp.Name(fn => fn.pos).IgnoreMalformed(true))
)
)
.Object<TripInsightSegmt>(o => o
.Name(n => n.segmts)
//.AutoMap()
.Properties(lp => lp.GeoPoint(gp => gp.Name(fn => fn.fpos).IgnoreMalformed(true))
.GeoPoint(gp => gp.Name(fn => fn.tpos).IgnoreMalformed(true))
)
)
.Object<TripInsightGFence>(o => o
.Name(n => n.gfence)
//.AutoMap()
.Properties(lp => lp.GeoPoint(gp => gp.Name(fn => fn.pos).IgnoreMalformed(true)))
)
)
).RequestConfiguration(r => r
.DisableDirectStreaming()
)
.InitializeUsing(esh.indexConfig));
以下是映射的结果
