• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty lang xa hoi. lieu ((va thai) OR (van thai)) tuc va danh vi ((cua tre) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty lang xa hoi. lieu ((va thai) OR (van thai)) tuc va danh vi ((cua tre) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty lang xa hoi. lieu ((va thai) OR (van thai)) tuc va danh vi ((cua tre) or (su triet))*".
