title: $geoWithin with $in or $or
body: <p>I need some help with an issue, the thing is very simple, I've tried this:</p>
  
  <pre><code>db.things.find({"position": {'$in': [{"$geoWithin":{"$center": [[10,10],10] } }, null ] } })
  </code></pre>
  
  <p>and this:</p>
  
  <pre><code>db.things.find({$or: [{"position":{"$geoWithin":{"$center":[[10,10],10]}}, "position": null}]})
  </code></pre>
  
  <p>Neither of them work, I need all the "things" in that circle or "things" that don't have the position field. I have to add that the query returns only the document that don't have the field, excluding the docs that are in the circle.</p>
  
  <p>Any help will be apreciated.</p>
  
  <p>Thanks</p>
