title: Does Rails 4 have support for OR queries
body: <p>So in Rails 4 the long desired feature to use <code>not</code> queries has been added.</p>
  
  <pre><code>Article.where.not(title: 'Rails 3')
  </code></pre>
  
  <p>Has similar support been added for <code>or</code> queries, or are they planning to make it. I couldn't find anything by browsing through the release notes.</p>
  
  <p>Obviously I tried</p>
  
  <pre><code>Article.where(title: 'Rails 3').or(title: 'Rails 4')
  </code></pre>
  
  <p>But that does not work.</p>
