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