• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((lang van) OR (hoang van)) hoi. thieu nien bach hue may tinh via cua triet~.
• Adding a wildcard symbol may retrieve word variants: thu sach ty ((lang van) or (hoang van)) hoi. thieu nien bach hue may tinh via cua triet*.
