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