  索引：

  [Completion(Name = "FieldNameSuggest")]
      public CompletionField Suggest
      {
          get
          {
              List<string> data = new List<string>();
              data.AddRange(new List<string>() {"word1",word2"word3",... });//for suggest
              return new CompletionField()
              {
                  Input = data,
                  Weight = 1
              };
          }
      }
  

  获得建议：

  查询制作：

  var sugContainer = new SuggestContainer
              {
                  { "completion-suggest", new SuggestBucket
                      {
                          Prefix ="word",//text for search
                          Completion = new CompletionSuggester
                          {
                              //Fuzzy = new FuzzySuggester
                              //{
                              //    Fuzziness = Fuzziness.Auto,
                              //    MinLength = 1,
                              //    PrefixLength = 2,
                              //    Transpositions = true,
                              //    UnicodeAware = false
                              //},
                              Analyzer = "simple",
                              Field =new Field("FieldNameSuggest"),
                              Size =10, //SuggestionCount
                              SkipDuplicates=true,
                          }
                      }
                  }
              };
  

  最终用于搜索：

  var Result = Client.Search<T>(new SearchRequest<T>
              {
                  Suggest = sugContainer ,
                  ...
              });
