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