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