• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan yuan li chen ((zheng min) OR (((cheng ming) OR (chen ping)))) jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yuan li chen ((zheng min) or (((cheng ming) OR (chen ping)))) jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yuan li chen ((zheng min) or (((cheng ming) OR (chen ping)))) jeong shu ;*.
