• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang OR wing) OR lang) yang yi yu cheng leon yu ((zheng zhi) OR (chen zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wing) or lang) yang yi yu cheng leon yu ((zheng zhi) OR (chen zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wing) or lang) yang yi yu cheng leon yu ((zheng zhi) OR (chen zhi)) ;*.
