title: Re-query a query in Laravel
body: <p>For example, if I have this:</p>
  
  <pre><code>$user = User::where('color', 'red')
      -&gt;get();
  </code></pre>
  
  <p>How can I query this variable, like:</p>
  
  <pre><code>$requery = $user-&gt;where('age', '25')
      -&gt;get();
  </code></pre>
  
  <p>Thanks.</p>
