• If you are trying to use Boolean operators, they must be ALL CAPS: ((liang sun) OR (liang dan)) lanka how best chan kang ((young seo) OR (young er)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((liang sun) or (liang dan)) lanka how best chan kang ((young seo) OR (young er)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((liang sun) or (liang dan)) lanka how best chan kang ((young seo) OR (young er)) ;*.
