• Performing a fuzzy search may retrieve terms with similar spellings: yan sudan chen yun wang ((((yang jin) OR (yang jun))) or (yang xi)) ((wong shiu) or (kong saur)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yan sudan chen yun wang ((((yang jin) OR (yang jun))) OR (yang xi)) ((wong shiu) OR (kong saur)) ;*.
