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