• If you are trying to use Boolean operators, they must be ALL CAPS: yeung ((kang can) OR (kang han)) china won ((yang jin) OR (yang jui)) ((tong hui) OR (wang wei)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yeung ((kang can) OR (kang han)) china won ((yang jin) or (yang jui)) ((tong hui) or (wang wei)) ;~".
• Adding a wildcard symbol may retrieve word variants: yeung ((kang can) OR (kang han)) china won ((yang jin) or (yang jui)) ((tong hui) or (wang wei)) ;*.
