C# 为什么使用NEST的自定义分析器的排序嵌套ElasticSearch返回无效结果？

使用elasticSearch v6.2.4，我希望根据HMI中的用户选择对结果进行排序

这对于我的SearchableCondition中的大多数元素来说都是成功的，但对于涉及血管的成员来说却不是

我对ES还很陌生，读了很多关于查询和排序等可能的变体的文章后，我觉得有点不知所措

课程的简短版本：

public class SearchableSituation : IEquatable<SearchableSituation>
{
    //Other members
    public IEnumerable<SearchableInvolvedVessel> InvolvedVessels { get; set; }
}

}

我正在尝试将我的查询构建为：

var sortedResult = await _client.SearchAsync<SearchableSituation>(s => s
.Index(_situationIndexer.IndexName)
.From(message.Query.SearchResultsFrom)
.Size(message.Query.SearchResultsSize)
.Sort(sort => sort.Ascending(f => f.Status)
    .Field(x => x.Nested(y => y.Path(p => p.InvolvedVessels))
        .Field(v => v.InvolvedVessels.First().VesselName.Suffix("keyword"))
        .Field("name.singleTerm")
        .Order(sortOrder)))
.Query(q => q
    .Bool(m => m
        .Must(queries))));

我尝试了许多不同的路径、字段和后缀选项，但没有成功，我开始觉得有点卡住了

有人能告诉我哪里出了问题吗？

所以，在VesselName映射中添加一个额外的字段会产生一个有效的结果

.Text(t => t
.Name(nn => nn.VesselName)
.Fields(f => f
    .Text(tk => tk
        .Name("singleTerm") //adding sub-field with keyword analyzer to index 'Name' property to include single term search when using phrase_prefix queries.
        .Analyzer("keywordWithCaseIgnore"))//))
    .Keyword(k => k          //<--- These two lines
        .Name("keyword"))))  //<---

您能否包括来自

sortedResult.DebugInformation

的详细信息？应该包含关于错误本身的更多详细信息。更新了post@Rob

var sortedResult = await _client.SearchAsync<SearchableSituation>(s => s
.Index(_situationIndexer.IndexName)
.From(message.Query.SearchResultsFrom)
.Size(message.Query.SearchResultsSize)
.Sort(sort => sort.Ascending(f => f.Status)
    .Field(x => x.Nested(y => y.Path(p => p.InvolvedVessels))
        .Field(v => v.InvolvedVessels.First().VesselName.Suffix("keyword"))
        .Field("name.singleTerm")
        .Order(sortOrder)))
.Query(q => q
    .Bool(m => m
        .Must(queries))));
