• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((hanh trung) OR (manh trung)) cua ((nhung cong) OR (thong cong)) van toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh trung) or (manh trung)) cua ((nhung cong) OR (thong cong)) van toan cau*".
