• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang ((((ma hoi) OR (ma hoa))) or (mai hoi)). hiem he nam thu xa danh hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang ((((ma hoi) OR (ma hoa))) OR (mai hoi)). hiem he nam thu xa danh hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang ((((ma hoi) OR (ma hoa))) or (mai hoi)). hiem he nam thu xa danh hai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang ((((ma hoi) OR (ma hoa))) or (mai hoi)). hiem he nam thu xa danh hai cua triet*.
