• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang fan) OR (yang yang)) hua hong sheng ((jin hong) OR (((kim song) OR (kim eung)))) seo ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang fan) or (yang yang)) hua hong sheng ((jin hong) or (((kim song) OR (kim eung)))) seo ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang fan) or (yang yang)) hua hong sheng ((jin hong) or (((kim song) OR (kim eung)))) seo ;*.
