• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan zwan) OR (yan clan)) goals case thinking form ((wenn die) OR (song thin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan zwan) OR (yan clan)) goals case thinking form ((wenn die) or (song thin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan zwan) OR (yan clan)) goals case thinking form ((wenn die) or (song thin)) ;*.
