• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky nang ((ho hoi) or (hoi hoi)). hieu ve ((cam tu) OR (cam thu)) van anh de cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky nang ((ho hoi) OR (hoi hoi)). hieu ve ((cam tu) OR (cam thu)) van anh de cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky nang ((ho hoi) or (hoi hoi)). hieu ve ((cam tu) OR (cam thu)) van anh de cua triet*".
