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