• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sac ky) OR (cac ky)) tang xa hoi. hieu ve cam ((xuc va) OR (thuc va)) danh ve va trien.
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) or (cac ky)) tang xa hoi. hieu ve cam ((xuc va) or (thuc va)) danh ve va trien*.
