• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((li zhang) OR (man han)) ((run john) OR (turn john)) bonn min jin ming ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((li zhang) or (man han)) ((run john) OR (turn john)) bonn min jin ming ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((li zhang) or (man han)) ((run john) OR (turn john)) bonn min jin ming ;*.
