• Performing a fuzzy search may retrieve terms with similar spellings: su xac ky nang ((((ma hoi) OR (me hoi))) or (mai hoi)). thien van cau truc ban thanh vi va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky nang ((((ma hoi) OR (me hoi))) OR (mai hoi)). thien van cau truc ban thanh vi va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky nang ((((ma hoi) OR (me hoi))) or (mai hoi)). thien van cau truc ban thanh vi va triet".
• Adding a wildcard symbol may retrieve word variants: su xac ky nang ((((ma hoi) OR (me hoi))) or (mai hoi)). thien van cau truc ban thanh vi va triet*.
