• Removing quotes may allow a broader search: (((( serie policiaca publicaa. ) OR ( entre politica publicaa. ))) OR ( serie politicas public. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("serie policiaca publicaa.") OR ("entre politica publicaa."))) OR ("serie politicas public."))*.
