• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: using python programming AND algorithm ((black activity) OR (block activity)) gate python computer~.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "using python programming and algorithm ((black activity) OR (block activity)) gate python computer~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: using python programming and algorithm ((black activity) OR (block activity)) gate python computer*.
