Perhaps you should try some spelling variations:
"serie policiaca public." » "serie politica publicas.", "serie politico publico."
"entre politicas publicas." » "entre politica publicas.", "en politicas publicas.", "sobre politicas publicas."
"elite politica publica." » "elites politicas publica.", "etica politica publica.", "entre politica publica."

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