• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (yuan chang)) yang a gene hong hai ((kong saur) OR (kong your)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yuan chang)) yang a gene hong hai ((kong saur) OR (kong your)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yuan chang)) yang a gene hong hai ((kong saur) OR (kong your)) ;*.
