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