• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (su sach)) ky nang x hoi. hieu va cham ((tuc va) OR (duc va)) tinh de cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (su sach)) ky nang x hoi. hieu va cham ((tuc va) or (duc va)) tinh de cua tre*.
