• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yong)) liang hua gene ((sang min) OR (song min)) jeong 情 ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang yong)) liang hua gene ((sang min) or (song min)) jeong 情 ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) OR (wang yong)) liang hua gene ((sang min) or (song min)) jeong 情 ;*.
