• If you are trying to use Boolean operators, they must be ALL CAPS: (( yu ming cheng _ she ji song shu ) OR ( ((fu ling) OR (fu ying)) chen x she i young soo )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( yu ming cheng _ she ji song shu ) or ( ((fu ling) OR (fu ying)) chen x she i young soo ))".
• Adding a wildcard symbol may retrieve word variants: (( yu ming cheng _ she ji song shu ) or ( ((fu ling) OR (fu ying)) chen x she i young soo ))*.
