title: Mongoose query to sort, skip and limit
body: <p>Here is my mongoose code which does sorting
  And pagination. Here when i am removing sorting
  or adding other type of sort no result is coming.
  And i have 3000 documents in db</p>
  <pre><code>  res = await Question.find(filters)
    .sort({'_id': &quot;-1&quot;})
    .skip(args.skip ? parseInt(args.skip) : 0)
    .limit(args.limit ? parseInt(args.limit) : 100)
    .exec();
  </code></pre>
  <p>Please take a look</p>
