• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sach) OR (chieu sang)) - nhanh tinh cua nhung song van ((toan tap) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sach) OR (chieu sang)) - nhanh tinh cua nhung song van ((toan tap) or (toan ban))*.
