• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang ((((ma hoi) OR (mai hoi))) or (ma hoa)). thien van nam qua ban hang vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang ((((ma hoi) OR (mai hoi))) OR (ma hoa)). thien van nam qua ban hang vai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang ((((ma hoi) OR (mai hoi))) or (ma hoa)). thien van nam qua ban hang vai cuu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang ((((ma hoi) OR (mai hoi))) or (ma hoa)). thien van nam qua ban hang vai cuu tre*.
