I think no matter what "operation" is desired, the search is still
lacking.

Further research has shown that this is an often requested feature and
has been wanted since 2001:

I have been looking into using the Expression match criterion, but I
only just saw that it was a Scheme expression. I know nothing about
Scheme at this time.

Prior to that bit, I was thinking of writing a Python script to load the
addressbook database (it is in Berkeley Hash DB format) and allowing
various searches. The addressbook is stored as a hash of VCARD entries.*

Alternatively, I was thinking to write something in C/C++ to call the
back-end directly, hopefully looking at the source for
evolution-addressbook-export for guidance.

None of this is particularly easy for me as I am learning as I go, and
doing it when I have time. I don't mind contributing any resulting code
to the project, but I will need guidance to do it correctly.

* Complicating this on Debian 5.0.2 (Lenny) is the fact that python is
linked against Berkeley DB 4.5 and Evolution against 4.6. So I also have
to backport the address databases to the earlier version. Aarh!
