• If you are trying to use Boolean operators, they must be ALL CAPS: ((((dong yuan) OR (dong nan))) OR (dong yang)) wang i gene ((liang tan) OR (yang yang)) hong seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dong yuan) OR (dong nan))) or (dong yang)) wang i gene ((liang tan) or (yang yang)) hong seo ;~".
• Adding a wildcard symbol may retrieve word variants: ((((dong yuan) OR (dong nan))) or (dong yang)) wang i gene ((liang tan) or (yang yang)) hong seo ;*.
