• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yanling) or (wang yangming)) hans dr tan yang di ((congo can) OR (congo call)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yanling) or (wang yangming)) hans dr tan yang di ((congo can) OR (congo call)) ;*.
