elasticsearch - Elasticsearch NEST V2完成上下文映射

Question

我具有提供自动完成功能的功能，该功能仅返回索引中某种类型的文档。

我有自动完成建议程序，无需应用上下文。但是，当我尝试映射上下文时，它将失败。

这是我的映射。

.Map<MyType>(l => l
.Properties(p => p
    .Boolean(b => b
        .Name(n => n.IsArchived)
    )
    .String(s => s
        .Name(n => n.Type)
        .Index(FieldIndexOption.No)
    )
    .AutoMap()
    .Completion(c => c
        .Name(n => n.Suggest)
        .Payloads(false)
        .Context(context => context
            .Category("type", cat => cat
                .Field(field => field.Type)
                .Default(new string[] { "defaultType" })
            )
        )
    )
)

不知道我在做什么错，因为intellisense或build中没有任何错误。

The Context Suggester mapping不正确，无法原样编译； AutoMap()不是PropertiesDescriptor<T>的方法，而是PutMappingDescriptor<T>的方法。看看the completion suggester mapping that is used as part of the integration tests。它应该如下所示

public class MyType
{
    public bool IsArchived { get; set;}

    public string Type { get; set;}

    public  CompletionField<object> Suggest { get; set;}
}

client.Map<MyType>(l => l
    .AutoMap()
    .Properties(p => p
        .Boolean(b => b
            .Name(n => n.IsArchived)
        )
        .String(s => s
            .Name(n => n.Type)
            .Index(FieldIndexOption.No)
        )

        .Completion(c => c
            .Name(n => n.Suggest)
            .Context(context => context
                .Category("type", cat => cat
                    .Field(field => field.Type)
                    .Default("defaultType")
                )
            )
        )
    )
);

这导致以下映射

{
  "properties": {
    "isArchived": {
      "type": "boolean"
    },
    "type": {
      "type": "string",
      "index": "no"
    },
    "suggest": {
      "type": "completion",
      "context": {
        "type": {
          "type": "category",
          "path": "type",
          "default": [
            "defaultType"
          ]
        }
      }
    }
  }
}
