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