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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("sobre politicas public.") OR ("serie politicas public."))) or ("serie policiaca publicaa."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("sobre politicas public.") OR ("serie politicas public."))) OR ("serie policiaca publicaa."))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"sobre politicas public.\") OR (\"serie politicas public.\"))) or (\"serie policiaca publicaa.\"))*".
• Removing quotes may allow a broader search: (((( sobre politicas public. ) OR ( serie politicas public. ))) or ( serie policiaca publicaa. ))*.
