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