• If you are trying to use Boolean operators, they must be ALL CAPS: (( ju liu feng xu she ((xi cong) OR (tri cong)) shu ) OR ( ju liang shen xi she ji yong soo )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ju liu feng xu she ((xi cong) OR (tri cong)) shu ) or ( ju liang shen xi she ji yong soo ))".
• Adding a wildcard symbol may retrieve word variants: (( ju liu feng xu she ((xi cong) OR (tri cong)) shu ) or ( ju liang shen xi she ji yong soo ))*.
