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