• If you are trying to use Boolean operators, they must be ALL CAPS: theo tieu sach - ((nhanh dung) OR (nhanh hung)) thi nhung duong ((manh toan) OR (thanh toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - ((nhanh dung) OR (nhanh hung)) thi nhung duong ((manh toan) or (thanh toan)) cau".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - ((nhanh dung) OR (nhanh hung)) thi nhung duong ((manh toan) or (thanh toan)) cau*.
