• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang kang ((chen shen) OR (china shen)) chang kwok ((wang yue) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang kang ((chen shen) OR (china shen)) chang kwok ((wang yue) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang kang ((chen shen) OR (china shen)) chang kwok ((wang yue) or (hong yu)) ;*.
