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