• If you are trying to use Boolean operators, they must be ALL CAPS: (( yu liu cheng xu she ji ((cong shu) OR (nong shu)) ) OR ( tu qiang chen xi she ji kyung soo )).
• Adding a wildcard symbol may retrieve word variants: (( yu liu cheng xu she ji ((cong shu) or (nong shu)) ) or ( tu qiang chen xi she ji kyung soo ))*.
