• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((chieu sang) OR (chieu xanh))) OR (hieu lang)) - canh tranh luan dung cong anh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((chieu sang) OR (chieu xanh))) or (hieu lang)) - canh tranh luan dung cong anh toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu sang) OR (chieu xanh))) or (hieu lang)) - canh tranh luan dung cong anh toan tap*.
