• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - canh tranh cua nhu phuong ((trinh toan) OR (tinh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sach)) - canh tranh cua nhu phuong ((trinh toan) OR (tinh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sach)) - canh tranh cua nhu phuong ((trinh toan) OR (tinh toan)) cau*.
