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