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