• Performing a fuzzy search may retrieve terms with similar spellings: te sach y mang ((may hoi) or (may thoi)). hieu ve nhan duc va danh ((tu cua) OR (vu cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y mang ((may hoi) OR (may thoi)). hieu ve nhan duc va danh ((tu cua) OR (vu cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y mang ((may hoi) or (may thoi)). hieu ve nhan duc va danh ((tu cua) OR (vu cua)) triet*".
