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