• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: (( decrease NOT decrease decrease processes ) OR ( vpython collisions tool python programming ))~.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "(( decrease not decrease decrease processes ) OR ( vpython collisions tool python programming ))~".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (( decrease not decrease decrease processes ) OR ( vpython collisions tool python programming ))*.
