title: Redis get multiple sorted sets?
body: <p>I have multiple sorted sets, which I have named by keys like:</p>
  
  <pre><code>hello:user_id:2015-01-01
  hello:user_id:2015-01-02
  hello:user_id:2015-01-03
  hello:user_id:2015-01-04
  etc.
  </code></pre>
  
  <p>Is it possible to get all of these sets for dates between <code>hello:user_id:2015-01-01</code> and <code>hello:user_id:2015-01-04</code> ?</p>
