Hi I am looking for a way of displaying a bunch of pages spread out randomely over a large site on a single page like a search result or some sort of list linking to the pages.

Background:
40 departments use and create their own various "service" pages for whatever they do. these are mixed in with their regular content.
The site has a central "Services" page where I would like to have a list that updates itself based on what these departments are putting out on the site under that category (I was thinking of making them enter a code in the keyword for each of these pages that could be picked up in a search)

Is there a way of making a stand alone 'canned' search result or is there a module out there that will produce this type of report? Preferrably a free module.

Thanks for your input
Mike
