• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((trinh tin) OR (trinh tu)) - thanh thang cho chuong huong ((dan than) OR (manh toan)) ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((trinh tin) OR (trinh tu)) - thanh thang cho chuong huong ((dan than) or (manh toan)) ban".
• Adding a wildcard symbol may retrieve word variants: doc ((trinh tin) OR (trinh tu)) - thanh thang cho chuong huong ((dan than) or (manh toan)) ban*.
