• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) or (wang liang)) yong human gene bank can ((non sacu) OR (union sacu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) or (wang liang)) yong human gene bank can ((non sacu) OR (union sacu)) ;*.
