• If you are trying to use Boolean operators, they must be ALL CAPS: doc hieu xanh - ((((hoang manh) OR (hoang anh))) OR (lanh tranh)) cua khong cang van thanh tap~.
• Adding a wildcard symbol may retrieve word variants: doc hieu xanh - ((((hoang manh) or (hoang anh))) or (lanh tranh)) cua khong cang van thanh tap*.
