• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( j cent nerve cyst due ) OR ( ii ventral nerve can dcs ))) OR ( j benign neck cyst due ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( j cent nerve cyst due ) OR ( ii ventral nerve can dcs ))) OR ( j benign neck cyst due ))*.
