• The words AND, OR and NOT may confuse the search; try adding quotes: "((rol{acute}proactiva OR prod{acute}acticas) OR (pro{acute}actica OR peroffd{acute}actina)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((rol{acute}proactiva OR prod{acute}acticas) OR (pro{acute}actica OR peroffd{acute}actina)) ;*.
