• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (hoc sach)) y nang ma hoi. hieu ve cham tuc va thanh ve ((cua triet) OR (va thiet))~.
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (hoc sach)) y nang ma hoi. hieu ve cham tuc va thanh ve ((cua triet) or (va thiet))*.
