• If you are trying to use Boolean operators, they must be ALL CAPS: ((yu chen) OR (huang chang)) yan li chen zhang ((min hong) OR (amin hong)) seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yu chen) or (huang chang)) yan li chen zhang ((min hong) OR (amin hong)) seo ;~".
• Adding a wildcard symbol may retrieve word variants: ((yu chen) or (huang chang)) yan li chen zhang ((min hong) OR (amin hong)) seo ;*.
