• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chinh sach)) - hung ((thang va) OR (hang va)) phuong cong manh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chinh sach)) - hung ((thang va) OR (hang va)) phuong cong manh toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chinh sach)) - hung ((thang va) OR (hang va)) phuong cong manh toan cau*.
