• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (doi chieu)) xanh - canh manh cua nhung ((huong van) OR (duong van)) thanh tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) xanh - canh manh cua nhung ((huong van) or (duong van)) thanh tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) xanh - canh manh cua nhung ((huong van) or (duong van)) thanh tap*.
