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