title: MONGO DB Like Operator
body: <p>I'm using JavaScript to query an API based on a Mongo DB.</p>
  
  <p>I would need filter the result based on LIKE operator, something similar to</p>
  
  <pre><code>select * from playlist where title like '%a%'
  </code></pre>
  
  <p>At the moment I call this URL</p>
  
  <pre><code>var assetUrl = 'https://example.com/playlist?oauth_token=' + accessToken + '&amp;account=XXX'+ '&amp;fields={"title":true,"splash":true,"description":true,"source":true}'+ '&amp;criteria={"title":/.*a.*/}';
  </code></pre>
  
  <p>With no success (Return 0 objects).</p>
  
  <p>I would like to know if I should use Regular Expressions instead and how to use them in this context. Thanks</p>
