Perhaps you should try some spelling variations:
"ser politicos republica." » "ser politico republicano.", "ser criticos republica.", "ser politicas republicanas.", "de politicos republica.", "serie politicas republica.", "usos politicos republica."
"serie politica publicas." » "serie politicas publicas.", "serie politica publica.", "serie politica publicaciones.", "serie policiaca publicas.", "elite politica publicas."
"sobre politica publicas." » "sobre politicas publicas.", "sobre politica publica.", "sobre politica publicaciones."

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