• If you are trying to use Boolean operators, they must be ALL CAPS: wang ning ya hua (rene OR gene) yuan ((((hong hong) OR (how hong))) OR (hong ng)) tan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ning ya hua (rene or gene) yuan ((((hong hong) OR (how hong))) or (hong ng)) tan ;~".
• Adding a wildcard symbol may retrieve word variants: wang ning ya hua (rene or gene) yuan ((((hong hong) OR (how hong))) or (hong ng)) tan ;*.
