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