• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yuan li chen zhang fan ((((wang hui) OR (wang wei))) OR (((wang hui) OR (wang wei))i)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yuan li chen zhang fan ((((wang hui) OR (wang wei))) or (((wang hui) OR (wang wei))i)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yuan li chen zhang fan ((((wang hui) OR (wang wei))) or (((wang hui) OR (wang wei))i)) ;*.
