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