• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((wang yang) or (zhang jing)) lin li cong moving ((closed model) OR (closed vowels)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((wang yang) or (zhang jing)) lin li cong moving ((closed model) OR (closed vowels)) ;*.
