• Fazer uma busca fuzzy pode resultar em termos de grafias semelhantes: (((( j current nerve cyst dis ) or ( a central nerve cat dis ))) or ( j absent nerve system dis ))~.
• Caso esteja tentando utilizar os operadores booleanos, deve escrevê-los em Letras MAIÚSCULAS: (((( j current nerve cyst dis ) OR ( a central nerve cat dis ))) OR ( j absent nerve system dis )).
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (((( j current nerve cyst dis ) or ( a central nerve cat dis ))) or ( j absent nerve system dis ))*.
