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