• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang ma hoi. hieu ve cac xuc ((van hanh) OR (van anh)) di ((cua tuc) OR (cua thuoc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang ma hoi. hieu ve cac xuc ((van hanh) OR (van anh)) di ((cua tuc) or (cua thuoc))".
