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