• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (chieu xanh)) - canh tranh cua ((hang duong) OR (han duong)) van tuan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (chieu xanh)) - canh tranh cua ((hang duong) or (han duong)) van tuan cau".
