• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (yang yang)) zhang new start ((savings using) OR (things using)) a bit ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (yang yang)) zhang new start ((savings using) OR (things using)) a bit ;*".
