• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (((yang xi) OR (yang july))))ng ya human gender chang min ((hong 7) OR (hong a)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (((yang xi) or (yang july))))ng ya human gender chang min ((hong 7) OR (hong a)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (((yang xi) or (yang july))))ng ya human gender chang min ((hong 7) OR (hong a)) ;*.
