弹性搜索嵌套使用自定义分析创建索引不起作用

问题描述

我在使用 nesT 7.10.1 创建新索引时尝试添加自定义分析，但出现奇怪的错误。我什至尝试了官方 tutorial 中的代码，但仍然遇到相同的错误，这是我使用的代码示例

 var createIndexResponse = client.Indices.Create("questions",c => c
.Settings(s => s
    .Analysis(a => a
        .CharFilters(cf => cf
            .Mapping("programming_language",mca => mca
                .Mappings(new[]
                {
                    "c# => csharp","C# => Csharp"
                })
            )
        )
        .Analyzers(an => an
            .Custom("index_question",ca => ca
                .CharFilters("html_strip","programming_language")
                .Tokenizer("standard")
                .Filters("lowercase","stop")
            )
            .Custom("search_question",ca => ca
                .CharFilters("programming_language")
                .Tokenizer("standard")
                .Filters("lowercase","stop")
            )
        )
    )
)
.Map<Question>(mm => mm
    .AutoMap()
    .Properties(p => p
        .Text(t => t
            .Name(n => n.Body)
            .Analyzer("index_question")
            .SearchAnalyzer("search_question")
        )
    )
));

问题类

public class Question
{
    public string Body { get; set; }
}

我什至尝试使用分析器属性

public class Question
{
    [Text(Analyzer = "index_question",SearchAnalyzer = "search_question")]
    public string Body { get; set; }
}

仍然出现同样的错误，实际错误是
