• If you are trying to use Boolean operators, they must be ALL CAPS: ((((thuoc sach) OR (thu hoach))) OR (tu sach)) y nang cao hoi. hieu ve cao suc ban thanh di cua te~.
• Adding a wildcard symbol may retrieve word variants: ((((thuoc sach) or (thu hoach))) or (tu sach)) y nang cao hoi. hieu ve cao suc ban thanh di cua te*.
