• Performing a fuzzy search may retrieve terms with similar spellings: te sach ly nang ((cao hoi) OR (co hoc)). thien van nam luc van hanh vi ((cua triet) OR (su tien))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang ((cao hoi) OR (co hoc)). thien van nam luc van hanh vi ((cua triet) OR (su tien))".
• Adding a wildcard symbol may retrieve word variants: te sach ly nang ((cao hoi) OR (co hoc)). thien van nam luc van hanh vi ((cua triet) OR (su tien))*.
