title: How to query MongoDB with "like"
body: <p>I want to query something with SQL's <code>like</code> query:</p>
  <pre><code>SELECT * FROM users  WHERE name LIKE '%m%'
  </code></pre>
  <p>How can I achieve the same in MongoDB? I can't find an operator for <code>like</code> in <a href="http://www.mongodb.org/display/DOCS/Advanced+Queries" rel="noreferrer">the documentation</a>.</p>
