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