• If you are trying to use Boolean operators, they must be ALL CAPS: (("serie politicas public.") OR ((("serie politica publica.") OR ("elite politica publica."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"serie politicas public.\") or (((\"serie politica publica.\") OR (\"elite politica publica.\"))))~".
• Removing quotes may allow a broader search: (( serie politicas public. ) or ((( serie politica publica. ) OR ( elite politica publica. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("serie politicas public.") or ((("serie politica publica.") OR ("elite politica publica."))))*.
