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