我已经通过ElasticSearch Sense浏览器插件创建了以下索引，并且还创建了C＃Nest
Fluent映射。我可以在nGrams过滤器上表达Nest中除“ token_chars”以外的所有内容。我没有在C＃嵌套上获得强类型属性来添加“
token_chars”。有人遇到过同样的问题吗？

json和c＃设置如下所示。请帮忙

        "analysis": {
           "analyzer": {
              "str_index_analyzer": {
                 "filter": [
                    "lowercase",
                    "substring"
                 ],
                 "tokenizer": "keyword"
              },
           "filter": {
              "substring": {
                 "max_gram": "50",
                 "type": "nGram",
                 "min_gram": "2",
                 "token_chars": [ /*Not able to map */
                    "letter",
                    "digit"
                 ]
              }
           }

           var result = this._client.CreateIndex("mkfindex1", c => c
           .Analysis(a => a.Analyzers(an => an.Add("str_index_analyzer", new CustomAnalyzer()

                Filter = new string[] { "lowercase", "substring" },
                Tokenizer = "keyword"
            })).TokenFilters(bases => bases.Add("substring", new NgramTokenFilter()
            {
                MaxGram = 50,
                MinGram = 2,

                /*"token_chars": [//Not able to map
