Perhaps you should try some spelling variations:
factores biologicos » factores psicologicos, factores economicos
factores politicos » factores criticos, valores politicos, factores climaticos
aspectos politicos » aspectos juridicos, aspectos eticos, aspectos psicologicos
actores politicos » factores criticos
ciclos politicos » efectos politicos
actos politicos » efectos politicos, partidos politicos

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 (factores biologicos))\") or (((\"actores politicos\") or (((\"((actos politicos) OR (aspectos politicos))\") or (\"ciclos politicos\"))))))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"((factores politicos) OR (factores biologicos))\\") or (((\\"actores politicos\\") or (((\\"((actos politicos) or (aspectos politicos))\\") or (\\"ciclos politicos\\"))))))\"".
• Removing quotes may allow a broader search: (( ((factores politicos) OR (factores biologicos)) ) or ((( actores politicos ) or ((( ((actos politicos) or (aspectos politicos)) ) or ( ciclos politicos )))))).
