• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((ky sang) OR (ky tang)) ((ma hoi) or (ma hoa)). hieu ve cam duc va danh lai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky sang) OR (ky tang)) ((ma hoi) OR (ma hoa)). hieu ve cam duc va danh lai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky sang) OR (ky tang)) ((ma hoi) or (ma hoa)). hieu ve cam duc va danh lai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ky sang) OR (ky tang)) ((ma hoi) or (ma hoa)). hieu ve cam duc va danh lai cua tre*.
