Web search: "Nadji Lako"
A close friend of mine has recently published somewhat classical, centralized, web search site "Nadji Lako" (find easy). Try it out, it is not as fancy as Edgios but it is interesting on how many people are actually busy working on web searches (I know about three companies in Serbia, including one for which I work).
As far as I know, they use Lucene or SQL Server for indexing. Front end is implemented in .NET obviously.
You can visit the site here: http://www.nadjilako.com
