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