• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yan wang) OR (yang yang))) OR (chan eng)) yang di gene chang ha huong dao ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan wang) OR (yang yang))) or (chan eng)) yang di gene chang ha huong dao ;*".
