Spatial Partitioning and Physics Collision

I'm new in Bullet Physics, currently reading the manual.
I've set it up all seem to work well and integration was easy and straight forward.

I have a question.
I'm a little bit hazy on the spatial partitioning with physics part.
How does Bullet Physics resolve collision detection?
Does it create partitions of the world first up? ie spatial partitioning quad/octrees?
Or does it go the naive O(n^2) method?

If you can shed some light in the tunnel for me to clear things up a bit that would be just great.
Thanks in advance.
