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