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