• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elite politico publico.\") OR (\"elite politica publica.\"))) or (\"serie politicas publica.\"))~".
• Removing quotes may allow a broader search: (((( elite politico publico. ) OR ( elite politica publica. ))) or ( serie politicas publica. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("elite politico publico.") OR ("elite politica publica."))) or ("serie politicas publica."))*.
