Presented by Michael Busch, Search Engineer, Twitter
Lucene Revolution, Boston, October 2010

Lucene has for a while already a nice feature that we call "Near-realtime search" (NRT). The approach works well for a lot of applications, but we're currently working on an even better real-time solution in Lucene: directly searching IndexWriter's RAM buffer while do cuments are being added! This will dramatically improve indexing performance compared to NRT, and the search latency (the time it takes for a d ocument to become searchable) will shrink to a minimum - hence we will scratch the N in NRT! This talk will discuss this new approach and give an overview of the current status of Lucene's realtime-search branch.
