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