• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan wang) OR (yang yang)) yang zhi gene hong ((than hong) OR (thang long)) sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) or (yang yang)) yang zhi gene hong ((than hong) OR (thang long)) sau ;*".
