Perhaps you should try some spelling variations:
"serie policiaca publicaa." » "serie politica publica.", "serie politica publicas.", "serie politicas publicas."
"serie politica publicaa." » "serie politica publica.", "serie politica publicas.", "serie politicas publicas.", "serie politicas publicaa.", "sobre politica publicaa.", "elite politica publicaa."
"sobre politicas public." » "sobre politicas publicas.", "sobre politicas publicad.", "sobre politica publica.", "sobre politica public.", "serie politicas public."

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: (("sobre politicas public.") OR ((("serie politica publicaa.") OR ("serie policiaca publicaa."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sobre politicas public.\") or (((\"serie politica publicaa.\") OR (\"serie policiaca publicaa.\"))))~".
• Removing quotes may allow a broader search: (( sobre politicas public. ) or ((( serie politica publicaa. ) OR ( serie policiaca publicaa. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("sobre politicas public.") or ((("serie politica publicaa.") OR ("serie policiaca publicaa."))))*.
