• If you are trying to use Boolean operators, they must be ALL CAPS: su ((xac ky) OR (bac ky)) nang ((ho hoi) OR (hoi hoi)). hieu ve cam tuc ban thanh de cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((xac ky) OR (bac ky)) nang ((ho hoi) or (hoi hoi)). hieu ve cam tuc ban thanh de cua triet*".
