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