• If you are trying to use Boolean operators, they must be ALL CAPS: wang yanling ((yang july) OR (yang jun)) debt law main ((hong yeon) OR (dong myeon)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ((yang july) OR (yang jun)) debt law main ((hong yeon) or (dong myeon)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ((yang july) OR (yang jun)) debt law main ((hong yeon) or (dong myeon)) ;*.
