• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( j central nerve system dis ) OR ( i bent nerve _ dia ))) OR ( _ absent native a dia ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( j central nerve system dis ) OR ( i bent nerve _ dia ))) OR ( _ absent native a dia ))*.
