I have a collection where all form data is stored, each form with a different structure, but some forms with overlapping field names. I love mongo for the ease it proves here, allowing me to sort and aggregate totally different data based upon a few small common factors.

Now, for the UI, I need a list of all possible fields in the database so a user can choose which fields to view. I can't seem to find any mongo anything to return a list of fields, except for indexes.

How would I go about this?
