Perhaps you should try some spelling variations:
"aspectos psicologicos" » "aspectos economicos"
"factores politicos" » "factores criticos", "actos politicos", "valores politicos", "ffactores criticos"
"aspectos politicos" » "aspectos juridicos", "aspectos eticos"
"actores politicos" » "factores criticos"
"efectos politicos" » "derechos politicos", "efectos juridicos", "efectos fisicos"

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: (("factores politicos") OR ((((("actores politicos") OR ((("aspectos politicos") OR ("aspectos psicologicos"))))) OR ("efectos politicos"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"factores politicos\") or (((((\"actores politicos\") or (((\"aspectos politicos\") OR (\"aspectos psicologicos\"))))) or (\"efectos politicos\"))))~".
• Removing quotes may allow a broader search: (( factores politicos ) or ((((( actores politicos ) or ((( aspectos politicos ) OR ( aspectos psicologicos ))))) or ( efectos politicos ))))~.
• Adding a wildcard symbol may retrieve word variants: (("factores politicos") or ((((("actores politicos") or ((("aspectos politicos") OR ("aspectos psicologicos"))))) or ("efectos politicos"))))*.
