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