• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - hanh doanh cua ((bang song) or (hang cong)) ((thanh toan) OR (thanh hoa)) tap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh doanh cua ((bang song) or (hang cong)) ((thanh toan) OR (thanh hoa)) tap*.
