• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((nhanh mang) OR (hanh mang)) ((va dung) OR (tin dung)) trong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((nhanh mang) OR (hanh mang)) ((va dung) or (tin dung)) trong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((nhanh mang) OR (hanh mang)) ((va dung) or (tin dung)) trong dan toan cao*.
