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