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