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