• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((danh trung) OR (manh trung)) cua dong thuong han ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((danh trung) or (manh trung)) cua dong thuong han ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((danh trung) or (manh trung)) cua dong thuong han ((toan cau) OR (toan ban))*.
