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