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