• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"elite politicas publico.\") or (((\"sobre politicas publicas.\") OR (\"sobre politicas public.\"))))~".
• Removing quotes may allow a broader search: (( elite politicas publico. ) or ((( sobre politicas publicas. ) OR ( sobre politicas public. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("elite politicas publico.") or ((("sobre politicas publicas.") OR ("sobre politicas public."))))*.
