• If you are trying to use Boolean operators, they must be ALL CAPS: so sach thu huong ((ca hoi) OR (cau hoi)). hieu ve cam tuc van hang di ((cua triet) OR (su tien))~.
• Adding a wildcard symbol may retrieve word variants: so sach thu huong ((ca hoi) or (cau hoi)). hieu ve cam tuc van hang di ((cua triet) or (su tien))*.
