• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang x hoi. hieu va nhan luc ((van hanh) OR (ban hanh)) vi ((va triet) OR (su triet)).
• Adding a wildcard symbol may retrieve word variants: thu sach y nang x hoi. hieu va nhan luc ((van hanh) or (ban hanh)) vi ((va triet) or (su triet))*.
