• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (hoc sinh)) ty nang cach thoi. hieu ve cac qua ban hang toan xac trieu~.
• Adding a wildcard symbol may retrieve word variants: ((toc sach) or (hoc sinh)) ty nang cach thoi. hieu ve cac qua ban hang toan xac trieu*.
