• If you are trying to use Boolean operators, they must be ALL CAPS: (((("serie politica public.") OR ("serie policiaca public."))) OR ("sobre politicas publicas."))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"serie politica public.\") OR (\"serie policiaca public.\"))) or (\"sobre politicas publicas.\"))*".
• Removing quotes may allow a broader search: (((( serie politica public. ) OR ( serie policiaca public. ))) or ( sobre politicas publicas. ))*.
