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