• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chiet tach - thanh trung cam nhung ((cong dan) OR (cong tac)) ((than cap) OR (thanh cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chiet tach - thanh trung cam nhung ((cong dan) or (cong tac)) ((than cap) OR (thanh cac))*".
