• The words AND, OR and NOT may confuse the search; try adding quotes: "(( yu ling cheng _ she li song shu ) or ( fu ling ((chen x) OR (chen a)) she i young son ))".
• Adding a wildcard symbol may retrieve word variants: (( yu ling cheng _ she li song shu ) or ( fu ling ((chen x) OR (chen a)) she i young son ))*.
