I’m not sure how we managed to delete it but I have re-added the ability to search through the site.  The way we’ve organized the EPMGuidance.com site, every new article, or addition to the site is associated with a blog post which points to it.  So, using Search will list all blog posts which meet the search criteria.  The links from the post to the appropriate page within the site brings you to what you’re looking for with a single click.
Hopefully this will make the site a good deal more useful!
