• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan wang) OR (yang guang)) ((tan hua) OR (tuan china)) pei ((yang so) OR (yang yang)) long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan wang) OR (yang guang)) ((tan hua) OR (tuan china)) pei ((yang so) OR (yang yang)) long du ;*.
