• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((chieu xanh) OR (chieu sach)) - thanh truong cua nhung hong van ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doc ((chieu xanh) OR (chieu sach)) - thanh truong cua nhung hong van ((toan cao) or (toan ban))*.
