Perhaps you should try some spelling variations:
politicas publicad » politicas publicas, politica publica, politicos republica
politica publicasd » politicas publicas, politica publica, politica republicana
politica publicas » politicas publicas, politica publica, politica publicaciones
serie politica » serie politicas, serie policiaca, sobre politica

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 publicasd) OR (politicas publicad)). ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( serie politica publicas. ) or ( sobre ((politica publicasd) OR (politicas publicad)). ))~".
• Adding a wildcard symbol may retrieve word variants: (( serie politica publicas. ) or ( sobre ((politica publicasd) OR (politicas publicad)). ))*.
