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