We have a SQL Server database with a million-ish records that are indexed by Lucene.net through Nhibernate.Search. When we built the index for our classes, we tried to be extensive since the cost for indexing/retrieval was really small.

Typically I would have ran with the traditional 3-Tier approach but after spending some time looking around at various options I've got an inkling that some kind of ORM might be a better fi...
