Is that something...I'm at TechEd Barcelona right now and will be attending a session named "Microsoft Sharepoint Server 2007 for Search Code Name 'S2' - what is it and What's New" at 17:00 today. Now I'm checking my email through CommNet here and I just received the announcement that Microsoft released a new product called 'Microsoft Search Server Express'
So far, it looks to me like this is basically Sharepoint for Search. However...there will be an EXPRESS edition FOR FREE available!

Pretty cool...I'm wondering what the session will be about.. ;-)
