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