• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((nganh ky) OR (nganh y)) lang ((van hoi) OR (van hoa)). hieu ve cac duc va hoang thi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((nganh ky) OR (nganh y)) lang ((van hoi) or (van hoa)). hieu ve cac duc va hoang thi cua triet".
