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