• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - thanh trung cap dung phuong ((((dan than) OR (ban than))) OR (dan chan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - thanh trung cap dung phuong ((((dan than) OR (ban than))) or (dan chan)) cau".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - thanh trung cap dung phuong ((((dan than) OR (ban than))) or (dan chan)) cau*.
