• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - manh trung cua dang ((((cong thanh) OR (truong thanh))) OR (cong tan)) toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - manh trung cua dang ((((cong thanh) OR (truong thanh))) or (cong tan)) toan cao*".
