body: <p>How can I implement an autocomplete using redis?</p>
  
  <p>Say for example I have an array <code>["alfred","joel","jeff","addick"]</code>. When I type <code>a</code> I get <code>["alfred", "addick"]</code></p>
  
  <p>I hope you get the point. How can I implement this using redis commands efficiently(if possible but I think it is). It would be great if I could get some simple commands I can try out via telnet to mimic this behaviour.</p>
  
  <p>Thanks</p>
  
  <p>P.S: Merry x-mas to all of you :)</p>
