Perhaps you should try some spelling variations:
"aspectos politicos" » "aspectos juridicos", "aspectos eticos", "aspectos psicologicos"
"valores politicos" » "factores politicos", "actores politicos", "valores eticos"
"factores critica" » "factores criticos", "factor critico", "factores clinicos"
"factores clinico" » "factores clinicos", "factores criticos", "factores politico"

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