• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach doi tap, nghien cuu dong hoc nganh thong hoc mai ((hoi van) OR (hoi va)) nhan tao~".
• Adding a wildcard symbol may retrieve word variants: tu sach doi tap, nghien cuu dong hoc nganh thong hoc mai ((hoi van) OR (hoi va)) nhan tao*.
