title: Mongolite - distinct too big, 16mb cap
body: <p>I'm trying to query my database <code>ratingsChoices= m$distinct({'answers'})</code> but I get a <code>Warning: Error in : distinct too big, 16mb cap</code></p>
  
  <p>Is there a way around this error in <code>mongolite</code>? I've seen some similar problems with PyMongo, etc</p>
