• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - thanh trung ((cua thang) OR (xua thang)) luong sach toan tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - thanh trung ((cua thang) OR (xua thang)) luong sach toan tap*".
