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