• If you are trying to use Boolean operators, they must be ALL CAPS: te san ky nang ((cao hoi) OR (cao hoc)). thien van nam luc van ((tuan vi) OR (quan tri)) cua triet.
• Adding a wildcard symbol may retrieve word variants: te san ky nang ((cao hoi) or (cao hoc)). thien van nam luc van ((tuan vi) or (quan tri)) cua triet*.
