• If you are trying to use Boolean operators, they must be ALL CAPS: wang yuhan change jun ((wang yang) OR (((dan yang) OR (tan ying)))) jin song (shin OR sein) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yuhan change jun ((wang yang) or (((dan yang) or (tan ying)))) jin song (shin OR sein) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yuhan change jun ((wang yang) or (((dan yang) or (tan ying)))) jin song (shin OR sein) ;*.
