• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) OR (chieu sach)) - thanh doanh nhan chong cong ((van toan) or (van tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sang) OR (chieu sach)) - thanh doanh nhan chong cong ((van toan) or (van tuan)) cau*.
