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