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