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