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