• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) ky nang o hoi. hieu ve bac do van anh vi ((cua triet) OR (cua viet))~.
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) ky nang o hoi. hieu ve bac do van anh vi ((cua triet) or (cua viet))*.
