• The words AND, OR and NOT may confuse the search; try adding quotes: "(((pero{acute}aticas OR prod{acute}ifacticas) OR prof{acute}acticas) OR prod{acute}tactica) ;~".
• Adding a wildcard symbol may retrieve word variants: (((pero{acute}aticas OR prod{acute}ifacticas) OR prof{acute}acticas) OR prod{acute}tactica) ;*.
