• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky nang tai hoi. hieu ve cam ((((luc va) OR (tuc va))) OR (duc va)) thanh tai cua triet.
• Adding a wildcard symbol may retrieve word variants: su xac ky nang tai hoi. hieu ve cam ((((luc va) or (tuc va))) or (duc va)) thanh tai cua triet*.
