• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan clan) OR (yang fan)) juan rene ((yang jin) OR (yang di)) ((wong sam) OR (wong sau)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan clan) or (yang fan)) juan rene ((yang jin) or (yang di)) ((wong sam) OR (wong sau)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan clan) or (yang fan)) juan rene ((yang jin) or (yang di)) ((wong sam) OR (wong sau)) ;*.
