• If you are trying to use Boolean operators, they must be ALL CAPS: (( fei wang cheng xu she ((xi cong) OR (xi chang)) shu ) OR ( fu ling cheng _ she ji yong h )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( fei wang cheng xu she ((xi cong) OR (xi chang)) shu ) or ( fu ling cheng _ she ji yong h ))".
• Adding a wildcard symbol may retrieve word variants: (( fei wang cheng xu she ((xi cong) OR (xi chang)) shu ) or ( fu ling cheng _ she ji yong h ))*.
