• Performing a fuzzy search may retrieve terms with similar spellings: ((su sac) OR (su xac)) ky lang ((ha hoi) or (hoa hoi)). hieu ve cac duc va thanh lai chau triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky lang ((ha hoi) OR (hoa hoi)). hieu ve cac duc va thanh lai chau triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky lang ((ha hoi) or (hoa hoi)). hieu ve cac duc va thanh lai chau triet".
