• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chieu sang)) - ((thanh hang) or (thanh thang)) cua tong cong quang toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chieu sang)) - ((thanh hang) or (thanh thang)) cua tong cong quang toan ban*.
