• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (theo chu)) tinh - ((nang hang) OR (tnang hang)) cua hang cong dan toan ban~.
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (theo chu)) tinh - ((nang hang) or (tnang hang)) cua hang cong dan toan ban*.
