• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yang yang)) ryanling human gene ((bank can) OR (bank bank)) (hong or long) yu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang yang)) ryanling human gene ((bank can) OR (bank bank)) (hong or long) yu ;*.
