• "As palabras AND, OR e NOT podem gerar pesquisas incorrectas; tente utilizar aspas": "(((( j nat camp can now ) OR ( a nacl compared a non ))) OR ( 3.5 nacl chimp can new ))~".
• Se adicionar um carácter universal pode recuperar variações da palavra pesquisada: (((( j nat camp can now ) OR ( a nacl compared a non ))) OR ( 3.5 nacl chimp can new ))*.
