• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang ((co hoi) OR (co hoc)). thien van nam luc van ((thanh ve) OR (hanh ve)) cua triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang ((co hoi) OR (co hoc)). thien van nam luc van ((thanh ve) OR (hanh ve)) cua triet*.
