更新以显示工作样本

我试图在ElasticSearch中对一组用户名进行部分搜索.

四处寻找已经指明了我的nGram Tokenizer方向,但我对正确的实施感到难过并且没有得到任何结果.

这是我正在处理的项目中剥离的相关代码.

我尝试过不同的组合和搜索类型无济于事.

setup.cs

var client = new ElasticClient(settings.ConnectionSettings);

// (Try and) Setup the nGram tokenizer.
var indexSettings = new IndexSettings();
var custonAnalyzer = new CustomAnalyzer();

customAnalyzer.Tokenizer = "mynGram";
customAnalyzer.Filter = new List<string> { "lowercase" };

client.CreateIndex(settings.ConnectionSettings.DefaultIndex, indexSettings);

client.MapFromAttributes<Profile>();

// Create and add a new profile object.
var profile = new Profile
                  {
                      Id = "1",
                      Username = "Russell"
                  };


client.IndexAsync(profile);
