[Evolution] complicated(?) seach on address list and/or address book

[Victoria Spagnolo <v spagnolo pobox com>]

I want a way to search an address list and an address book, both "on this computer" to tell me two things for two different situations. In one case I need the total number of entries. And in the second case I need to know if the list contains at least one entry for each Department in my organisation and to inform me of the Departments that are missing. 
What are my options? My programming skills are 16 years out of date but if that is needed I'll consider it.

Evo 2.28.3 / Ubuntu 10.04
And apologies for not thanking those (whose names I don't remember) who helped me a few days ago.
