• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((thuoc sach) OR (thuat sach)) - thanh trung thanh dung cuong van ((nhanh cau) OR (nhanh ha)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((thuoc sach) OR (thuat sach)) - thanh trung thanh dung cuong van ((nhanh cau) or (nhanh ha))".
• Adding a wildcard symbol may retrieve word variants: theo ((thuoc sach) OR (thuat sach)) - thanh trung thanh dung cuong van ((nhanh cau) or (nhanh ha))*.
