• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan yuan lin ((chen zheng) or (chen aizheng)) jin ((song skin) OR (song min)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yan yuan lin ((chen zheng) or (chen aizheng)) jin ((song skin) OR (song min)) ;*.
