• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang so hai. lieu va cam ((((xuc ban) OR (xuat ban))) OR (quoc quan)) anh dai su triet.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang so hai. lieu va cam ((((xuc ban) or (xuat ban))) or (quoc quan)) anh dai su triet*.
