• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - nhanh quang cua thong thuong manh ((toan ban) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - nhanh quang cua thong thuong manh ((toan ban) or (van ban))*.
