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

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("serie politica publica.") OR ("elite politica publica."))) OR ("serie policiaca public."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"serie politica publica.\") OR (\"elite politica publica.\"))) or (\"serie policiaca public.\"))~".
• Removing quotes may allow a broader search: (((( serie politica publica. ) OR ( elite politica publica. ))) or ( serie policiaca public. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("serie politica publica.") OR ("elite politica publica."))) or ("serie policiaca public."))*.
