• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang liang) OR (yang yang)) hai gene tang min ((jeong seo) OR (jeong yeon)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang liang) OR (yang yang)) hai gene tang min ((jeong seo) or (jeong yeon)) ;*".
