Lucene, Open Source and the Cost of Experimentation
I was at a company a while back that was considering replacing a commercial vendor with a Lucene/Solr based solution.

(If you missed the training, see here for alternatives.)
During the conference, there were several talks on Lucene, Solr, Mahout and…
