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