• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ((ky lang) OR (ky nang)) xa hoi. hieu van cam xuc van thanh than ((cua triet) OR (cua viet)).
• Adding a wildcard symbol may retrieve word variants: su sai ((ky lang) or (ky nang)) xa hoi. hieu van cam xuc van thanh than ((cua triet) or (cua viet))*.
