• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan guang) OR (yang guang)) huan jie zhang kim ((young john) OR (wong john)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan guang) OR (yang guang)) huan jie zhang kim ((young john) or (wong john)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan guang) OR (yang guang)) huan jie zhang kim ((young john) or (wong john)) ;*.
