• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan zhang) OR (man can)) run wang ((yang ka) OR (yang fan)) ((song min) OR (song ming)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan zhang) or (man can)) run wang ((yang ka) OR (yang fan)) ((song min) or (song ming)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan zhang) or (man can)) run wang ((yang ka) OR (yang fan)) ((song min) or (song ming)) ;*.
