You should look into Full Text Search:

Suggesting SQL Server assumes thats the db backend, better to use Lucene or if you dont want to use java there's .Net, C and Ruby ports of the lucene.

Actually i wouldn't be surprised if SO is Lucene.Net based.

I believe they use the Full Text Search capabilities of SQL Server.

SQL Server Full text search

and as stackoverflow saying:

  • You're browsing through questions matching search terms search stackoverflow
  • Search within specific tags by adding them in brackets, like [tag] or [tag-2].
  • Enclose your search in "quotes" to match a phrase.
  • You can narrow your search by using the ~ (near) and - (not) operators before words.*

Not very well. If you need your site searchable, try adding a Google search box through Adsense (and setting up a sitemap).
