• If you are trying to use Boolean operators, they must be ALL CAPS: wang dan ((yang jin) OR (yang jun)) ((yi kang) OR (yi yang)) minh ((long du) OR (long d)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan ((yang jin) or (yang jun)) ((yi kang) or (yi yang)) minh ((long du) OR (long d)) ;*".
