• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((chieu xanh) OR (hieu lang))) OR (chieu sach)) - canh thanh qua dung song van ban hang~.
• Adding a wildcard symbol may retrieve word variants: theo ((((chieu xanh) or (hieu lang))) or (chieu sach)) - canh thanh qua dung song van ban hang*.
