• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: routing AND plot allocation algorithms ((in elasticity) OR (soil elasticity)) the python computer~.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "routing and plot allocation algorithms ((in elasticity) OR (soil elasticity)) the python computer~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: routing and plot allocation algorithms ((in elasticity) OR (soil elasticity)) the python computer*.
