• Performing a fuzzy search may retrieve terms with similar spellings: su sach hoi ((((lang ha) OR (long ha))) or (tang ma)) hoi. hieu ve cam luc va dan vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach hoi ((((lang ha) OR (long ha))) OR (tang ma)) hoi. hieu ve cam luc va dan vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach hoi ((((lang ha) OR (long ha))) or (tang ma)) hoi. hieu ve cam luc va dan vai cua triet".
