• The words AND, OR and NOT may confuse the search; try adding quotes: "((fang yan) OR (wang yang)) zhang hai ((center banks) or (die banken)) min jeong hyeok ;~".
• Adding a wildcard symbol may retrieve word variants: ((fang yan) OR (wang yang)) zhang hai ((center banks) or (die banken)) min jeong hyeok ;*.
