• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty nang ((o hoi) OR (co hoi)). hieu ve cham ((xuc va) OR (luc va)) thanh lam cua triet~.
• Adding a wildcard symbol may retrieve word variants: vu sach ty nang ((o hoi) or (co hoi)). hieu ve cham ((xuc va) or (luc va)) thanh lam cua triet*.
