Microsoft Site Server Search

Say hello to Microsoft® Site Server 3.0 and Microsoft Exchange Server 5.5. While Site Server provides the necessary features for full-text indexing, and search and knowledge delivery; Exchange Server provides the collaborative infrastructure and functionality that makes creating Internet newsgroups, threaded discussions, customer contact databases, and custom collaborative applications easy. Combine these two products and you have a knowledge management solution that can make your search page the most popular page on your intranet.
