• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hien sach - ((((canh manh) OR (van manh))) OR (lanh manh)) cua nhung cong tan toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hien sach - ((((canh manh) OR (van manh))) or (lanh manh)) cua nhung cong tan toan cau*".
