Perhaps you should try some spelling variations:
rol{acute}proactiva » rol{acute}proactivas, rol{acute}proactivo, rol{acute}practiva
prod{acute}cticas » proud{acute}cticas, pro{acute}cticas, prol{acute}cticas, prod{acute}acticas, prod{acute}icticas, prod{acute}eticas
prof{acute}tactica » prof{acute}practica
proffd{acute}lactima » proffd{acute}lactica, proffd{acute}lactama, proffd{acute}lastima

You may be able to get more results by adjusting your search query.

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