MongoChef Query IntelliShell versus QueryBuilder show different results
<p>The following query created AND run from Query Builder shows 10 result records. If I run the same code in IntelliShell I don't receive anything? What am I missing? </p>

<p>A more simple one again works.</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>db.user.find({

    em: {
        $regex: '.*\Qdirk\E.*',
        $options: 'i' 
    }
})</code></pre>
</div>
</div>
</p>

<p>A more simplistic one like this works again. Does MongoChef have issues with $regex ...</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>db.user.find({em: "dirk@test.com"})</code></pre>
</div>
</div>
