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