• If you are trying to use Boolean operators, they must be ALL CAPS: nan yan fang yuan ((cheng ping) OR (chen ping)) jia ((zhong siu) OR (kong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan fang yuan ((cheng ping) OR (chen ping)) jia ((zhong siu) or (kong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan yan fang yuan ((cheng ping) OR (chen ping)) jia ((zhong siu) or (kong siu)) ;*.
