• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang huang lin last ((savings using) OR (things using)) ((dong sin) OR (zhang wei)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang huang lin last ((savings using) OR (things using)) ((dong sin) or (zhang wei)) ;*".
