• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang ma hoi. hieu ve chat huu xa thanh lap ((((cua triet) OR (su triet))) OR (su viet))~.
• Adding a wildcard symbol may retrieve word variants: su sach ty nang ma hoi. hieu ve chat huu xa thanh lap ((((cua triet) or (su triet))) or (su viet))*.
