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