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