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