• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tai hang ((va hoi) OR (va hoa)). hieu ((va cam) OR (va cao)) tuc ban thanh vi cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tai hang ((va hoi) OR (va hoa)). hieu ((va cam) or (va cao)) tuc ban thanh vi cua triet~".
• Adding a wildcard symbol may retrieve word variants: te sach tai hang ((va hoi) OR (va hoa)). hieu ((va cam) or (va cao)) tuc ban thanh vi cua triet*.
