• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach dao tao, nghien ((cuu mon) OR (cua cong)) hoc nganh khong xuong nau hoi va nhan van".
• Adding a wildcard symbol may retrieve word variants: so sach dao tao, nghien ((cuu mon) OR (cua cong)) hoc nganh khong xuong nau hoi va nhan van*.
