• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - canh tranh thuc ((xung cong) OR (xuong cong)) tan toan ban.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - canh tranh thuc ((xung cong) or (xuong cong)) tan toan ban".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - canh tranh thuc ((xung cong) or (xuong cong)) tan toan ban*.
