• The words AND, OR and NOT may confuse the search; try adding quotes: "((perol{acute}lacticos OR prol{acute}eticos) OR (pro{acute}actina OR profd{acute}lactica)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((perol{acute}lacticos OR prol{acute}eticos) OR (pro{acute}actina OR profd{acute}lactica)) ;*.
