• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky sang ((ma hoi) OR (dai hoi)). lieu va dao xuc va hang ((di cua) OR (de cua)) viet~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky sang ((ma hoi) or (dai hoi)). lieu va dao xuc va hang ((di cua) or (de cua)) viet*.
