• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien nhanh) OR (tran thanh)) - ((canh ban) OR (canh dan)) quan nhung cong tan toan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien nhanh) or (tran thanh)) - ((canh ban) or (canh dan)) quan nhung cong tan toan ban*.
