theo chu » theo chieu, cho chu, chao chu

• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - hanh mang cua thuong huong dan ((toan cao) OR (toan tap))~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh mang cua thuong huong dan ((toan cao) or (toan tap))*.
