• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang x ho. lieu va hac duc va ((((thanh lap) OR (hanh lam))) OR (thanh hai)) chau triet.
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang x ho. lieu va hac duc va ((((thanh lap) or (hanh lam))) or (thanh hai)) chau triet*.
