Você pode obter mais resultados ajustando o argumento de busca.

• Fazer uma busca fuzzy pode resultar em termos de grafias semelhantes: (("based computational and computer program") OR ("advanced modulation _ computing program"))~.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "((\"based computational and computer program\") OR (\"advanced modulation _ computing program\"))".
• Remover as aspas pode possibilitar buscas mais amplas: (( based computational and computer program ) OR ( advanced modulation _ computing program )).
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (("based computational and computer program") OR ("advanced modulation _ computing program"))*.
