• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yong yan) OR (ying yang))) OR (dong yang)) 4 fan ying ((jin chang) OR (joon chang)) hay ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yong yan) or (ying yang))) or (dong yang)) 4 fan ying ((jin chang) OR (joon chang)) hay ;*".
