• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yan zhang) OR (hao zhang))) OR (han chang)) juan rene yang bin dann kam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan zhang) OR (hao zhang))) or (han chang)) juan rene yang bin dann kam ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan zhang) OR (hao zhang))) or (han chang)) juan rene yang bin dann kam ;*.
