title: Searching for values in Redis
body: <p>Is it possible to search for occurrences of a specific value in redis?</p>
  
  <p>It's easy enough to do the same for keys </p>
  
  <pre><code>SET firstname "John"
  
  KEYS f?rstname
  ["firstname"]
  </code></pre>
  
  <p>But can one search for all occurrences of "John" or better yet "J*hn" ?</p>
