• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang wang hui ((chen tan) OR (chen yang)) ((jin chang) or (can change)) (sar or star) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang wang hui ((chen tan) OR (chen yang)) ((jin chang) or (can change)) (sar or star) ;*.
