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

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