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