• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (wang yang)) yi yu ((chen shuang) OR (chen chung)) min kyung joon ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (wang yang)) yi yu ((chen shuang) OR (chen chung)) min kyung joon ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (wang yang)) yi yu ((chen shuang) OR (chen chung)) min kyung joon ;*.
