• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (hoc thieu)) sach - manh trung qua dung cong ((van than) OR (van tuan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) or (hoc thieu)) sach - manh trung qua dung cong ((van than) OR (van tuan)) cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc chieu) or (hoc thieu)) sach - manh trung qua dung cong ((van than) OR (van tuan)) cau*.
