• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dan) OR (wang yidan)) ((yan li) OR (yang jin)) chen zhang xin song (shin OR skin) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) OR (wang yidan)) ((yan li) or (yang jin)) chen zhang xin song (shin or skin) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) OR (wang yidan)) ((yan li) or (yang jin)) chen zhang xin song (shin or skin) ;*.
