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