我正在尝试使用nest 7.4和我从中找到的示例创建自动建议查询 https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/suggest-usage.html 但是我收到未找到Project和ProjectFilter的错误。 您能否让我知道我所缺少的东西。我认为Project可能引用了DTO对象，但事实并非如此，因为如果我用DTO替换项目，则会报错

void getSuggestions()
        {
            var settings = new ConnectionSettings(new Uri("http://localhost:9200"))
               .DefaultIndex(index);

            var client = new ElasticClient(settings);

            var results = client.Search<GenericSearchDto>(new SearchRequest<GenericSearchDto>
                      {
