使用NEST创建自定义令牌过滤器

经过一番搜索，我找到了一个解决方案：

var partialName = new CustomAnalyzer {     Filter = new List<string> {"lowercase", "name_ngrams", "standard", "asciifolding"},     Tokenizer = "standard" };var fullName = new CustomAnalyzer {     Filter = new List<string> {"standard", "lowercase", "asciifolding"},     Tokenizer = "standard" };client.CreateIndex("indexname", c => c     .Analysis(descriptor => descriptor         .TokenFilters(bases => bases.Add("name_ngrams", new EdgeNGramTokenFilter         {  MaxGram = 20,  MinGram = 2,  Side = "front"         }))         .Analyzers(bases => bases  .Add("partial_name", partialName)  .Add("full_name", fullName))     )     .AddMapping<Company>(m => m         .Properties(o => o  .String(i => i      .Name(x => x.Name)      .IndexAnalyzer("partial_name")      .SearchAnalyzer("full_name")  ))));
