• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu sach) OR (hien hanh)) - thanh trung cua thuong thuong van ((chat cau) OR (chat cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu sach) or (hien hanh)) - thanh trung cua thuong thuong van ((chat cau) OR (chat cao))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu sach) or (hien hanh)) - thanh trung cua thuong thuong van ((chat cau) OR (chat cao))*.
