• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "((\"advanced modulation _ computer programming\") OR (\"enhanced python python computer program\"))~".
• Remover as aspas pode possibilitar buscas mais amplas: (( advanced modulation _ computer programming ) OR ( enhanced python python computer program ))~.
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (("advanced modulation _ computer programming") OR ("enhanced python python computer program"))*.
