title: Getting recursively nested document - Mongoose / Mongodb
body: <p>I have a recursively nested schema just like comments work on a blog. What is the best way to pull an individually nested document out which may be several layers deep. </p>
  
  <p>I understand that you get the root document out, then drill down to the document you want, but in a recursive situation where the wanted document may be an unknown number of levels deep how should I retrive it. Loop through and do an if to see if its the correct one...?</p>
