• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cai) OR (tu bai)) ky tang van hoe. hieu ve cham hoc ban thanh hai ((cau treo) OR (su triet))~.
• Adding a wildcard symbol may retrieve word variants: ((tu cai) or (tu bai)) ky tang van hoe. hieu ve cham hoc ban thanh hai ((cau treo) or (su triet))*.
