That’s cool, I went to JavaBiN today (JUG Norway) and listened to Kristoffer Dyrkorn (BEKK Consulting) talk about Lucene and a project they implemented using it. A good talk with the basics and challenges for creating a good search. It basically comes down to knowing your data, target users and tweaking the results.
As I got back I found this article about the details behind The ServerSide search engine. It’s been a informative evening. Excellent. 🙂
