Perhaps you should try some spelling variations:
"publica administration" » "publica administracao" (Expand Search)
"publicooas administration" » "publicooas administracao" (Expand Search), "publicas administration" (Expand Search), "publicos administration" (Expand Search)
"publicosas administration" » "publicosas administracao" (Expand Search), "publicas administration" (Expand Search), "publicos administration" (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"publica administration\") OR (((\"publicooas administration\") OR (\"publicosas administration\"))))~".
• Removing quotes may allow a broader search: (( publica administration ) OR ((( publicooas administration ) OR ( publicosas administration ))))~.
• Adding a wildcard symbol may retrieve word variants: (("publica administration") OR ((("publicooas administration") OR ("publicosas administration"))))*.
