title: Can Redis do prefix matching?
body: <p>Lets say I have a set of cities in the world like so:</p>
  
  <pre><code>EUKLOND
  EUKMANC
  EUKEDIN
  EITROME
  EITMILA
  EITNAPE
  EFRPARI
  EFRAVIG
  EFRBRES
  </code></pre>
  
  <p>Where the first letter is continent, next two are country and the trailing 4 are an abbreviated city name.</p>
  
  <p>I would like to be able to search this set by passing in "E" which would return all the entries or EIT and retrieve all the entries for Italy or EFRPARI and get just the Paris entry.</p>
  
  <p>Is this something I can do with Redis?</p>
