• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( _ can computed can non ) OR ( j can computed a non ))) OR ( j a computers can newts ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( _ can computed can non ) OR ( j can computed a non ))) OR ( j a computers can newts ))*.
