• Performing a fuzzy search may retrieve terms with similar spellings: (((((("factores politicos") OR ("valores politicos"))) or ("ffactores criticos"))) 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 ("ffactores criticos"))) 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 (\"ffactores criticos\"))) or (((\"actores politicos\") or (\"actos politicos\"))))*".
• Removing quotes may allow a broader search: (((((( factores politicos ) OR ( valores politicos ))) or ( ffactores criticos ))) or ((( actores politicos ) or ( actos politicos ))))*.
