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