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