• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yin hang) OR (yin yang)) juan rene ((yang xi) OR (yang yi)) ((hong kong) OR (hong hong)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yin hang) OR (yin yang)) juan rene ((yang xi) or (yang yi)) ((hong kong) or (hong hong)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yin hang) OR (yin yang)) juan rene ((yang xi) or (yang yi)) ((hong kong) or (hong hong)) ;*.
