• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((wang yong) OR (wang yang)) human gene bank can ((non sacu) OR (non sans)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((wang yong) OR (wang yang)) human gene bank can ((non sacu) or (non sans)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((wang yong) OR (wang yang)) human gene bank can ((non sacu) or (non sans)) ;*.
