title: Pymongo: can I query a pymongo query object?
body: <p>I have a query in python using pymongo that works very well. It returns entries for a single user. Later on the script, I want to narrow this results. I want to iterate over each day, and query again for this user how many entries are there on this day alone. </p>
  
  <p>The question is: Do I need to make a new query, or can I query over the object I already have? </p>
  
  <p>Thanks</p>
