DB Design using Berkeley DB

This is my first posting to this group! :)

Can you guys point me to some sample design documents (for a simple
project) using Berkeley DB?

I'm working on a simple "Address Book" kinda project, which has to do
basic addition/deletion/updation of a contact, mailing list and
search. Also I would like the search to be as fast as possible. Any
suggestions on how to design this DB schema?

TIA!
