• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong yang) OR (yang yang)) i last ((things zhang) OR (cheng zhang)) dong bin ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) OR (yang yang)) i last ((things zhang) or (cheng zhang)) dong bin ;".
