• If you are trying to use Boolean operators, they must be ALL CAPS: cho ((chu xanh) OR (chieu xanh)) - hanh trang ((luan thuong) OR (luat thuong)) con dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) or (chieu xanh)) - hanh trang ((luan thuong) OR (luat thuong)) con dan toan cao".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) or (chieu xanh)) - hanh trang ((luan thuong) OR (luat thuong)) con dan toan cao*.
