弹性NEST中子文档的关键字映射

我现在学习了针对elasticsearch的Nest 6.x客户端我想在子文档中使用术语搜索。我有这个课程:

public class BaseTest
    {
        public string Id { get; set; }

        public SubBase SubDocument { get; set; }

        public Guid TypeId { get; set; }

        public string BaseTitel { get; set; }
    }
public class SubBase
    {
        public int Id { get; set; }
        public Guid IdGuid { get; set; }
        public string Titel { get; set; }
    }

并使用此映射创建索引:

.Mappings(mp => mp
                    .Map<BaseTest>(m => m
                        .Properties(pr => pr
                            .Keyword(kw => kw
                                .Name(nm => nm.BaseTitel)))
                        .Properties(pr => pr
                            .Keyword(kw => kw
                                .Name(nm => nm.TypeId)))
                        .Properties(pr => pr
                            .Keyword(kw => kw
                                .Name(nm => nm.SubDocument.Titel)))
                        .Properties(pr => pr
                            .Keyword(kw => kw
                                .Name(nm => nm.SubDocument.IdGuid)
                            ))))

wenn我尝试在BaseTest中搜索GUID(或GUID格式的字符串,我将SubBase.Titel保存为Guid for tests)值,但不在SubBase中。 要搜索我使用此查询:

.Query(q => q
 .ConstantScore(cs => cs
  .Filter(f => f
   .Term(t => t
    .SubDocument.Titel, "5d511b8a-37c7-40c1-a5c3-4de13e16e379"))))

更新
新映射:

.Mappings(mp => mp
                    .Map<BaseTest>(m => m
                        .Properties(pr => pr
                            .Keyword(kw => kw
                                .Name(nm => nm.BaseTitel)
                                .Name(nm => nm.TypeId)
                            )
                            .Object<SubBase>(o => o
                                .Name(n => n.SubDocument)
                                .Properties(p => p
                                    .Keyword(k => k
                                        .Name(n => n.Titel)
                                        .Name(n => n.IdGuid)))))))

现在我可以找到Guid属性,但不能找到类型字符串的值,例如&#34; 5d511b8a-37c7-40c1-a5c3-4de13e16e379&#34;
