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