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