• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( j bent nerve system dis ) OR ( i femoral merve can tdcs ))) OR ( j benito eva system dis ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( j bent nerve system dis ) OR ( i femoral merve can tdcs ))) OR ( j benito eva system dis ))*.
