• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( _ letter nerve cat dis ) OR ( a ventral nerve cn dcs ))) OR ( j augment nerve cat dis ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( _ letter nerve cat dis ) OR ( a ventral nerve cn dcs ))) OR ( j augment nerve cat dis ))*.
