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