"efectos politicos" » "efectos positivos", "aspectos politicos", "derechos politicos"
"actos politicos" » "aspectos politicos", "ciclos politicos", "partidos politicos"
"factores criticos" » "factores critico", "factores critica", "factores critical"

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

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