• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky nang ((((tao hoi) OR (tao khoi))) OR (cho hoc)). thien van nam luc van thanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky nang ((((tao hoi) OR (tao khoi))) or (cho hoc)). thien van nam luc van thanh vi cua triet".
