• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( j nat compare _ netw ) OR ( j nat compares cases new ))) OR ( j daza compared case netw ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( j nat compare _ netw ) OR ( j nat compares cases new ))) OR ( j daza compared case netw ))*.
