也许你应该尝试一些拼写变化:
"public administration" » "publica administration" (扩展搜索), "publico administration" (扩展搜索), "publicas administration" (扩展搜索), "public administracao" (扩展搜索)
"publicoos administration" » "publicaoos administration" (扩展搜索), "publicooos administration" (扩展搜索), "publicasoos administration" (扩展搜索), "publicoos administracao" (扩展搜索), "publicos administration" (扩展搜索), "publico administration" (扩展搜索), "publicas administration" (扩展搜索)
"publicoao administration" » "publicaoao administration" (扩展搜索), "publicooao administration" (扩展搜索), "publicasoao administration" (扩展搜索), "publicoao administracao" (扩展搜索), "publica administration" (扩展搜索), "publico administration" (扩展搜索), "publicas administration" (扩展搜索)

Você pode obter mais resultados ajustando o argumento de busca.

• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "((((\"public administration\") OR (\"publicoos administration\"))) OR (\"publicoao administration\"))~".
• Remover as aspas pode possibilitar buscas mais amplas: (((( public administration ) OR ( publicoos administration ))) OR ( publicoao administration ))~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (((("public administration") OR ("publicoos administration"))) OR ("publicoao administration"))*.
