我需要帮助，根据我的搜索字符串从列表中查找句子， 返回值时表示列表为空

internal void OrganizarCarrouselChatBot(List<clsProduto> produtos, string search, out ChatBotCarrouselViewModel carrousel)
{             

                string[] prodList = produto.Titulo.Split(' ');
                string[] encontrar = search.Split(' ');

                var sentencaQuery = (from sentenca in prodList
                                     let a = prodList
                                     where a.Distinct().Intersect(encontrar).Count() == encontrar.Count()
                                     select sentenca).ToList();

                foreach (string str in sentencaQuery)
                {
                    Console.WriteLine(str);
                }
}
