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