[Announce] Solr 3.4 with RankingAlgorithm 1.3, NRT support

Hi!

I am very excited to announce the availability of Solr 3.4 with 
RankingAlgorithm 1.3.

This version supports NRT and can update 10,000 docs / sec (MbArtists 
Index). MbArtists index is the example used in the Solr 1.4 Enterprise 
Book, has 43 fields so is quite realistic.

RankingAlgorithm 1.3 is 50-100% faster than version 1.2 so you should 
see a significant improvment in performance. An internal test that used 
to take 20mins to complete now completes in 10mins. You should also be 
able query a 10m wikipedia index (complete index) in <50 ms. 
RankingAlgorithm 1.3 now supports the entire Lucene Query Syntax, +/- 
and/or boolean queries.

You can get more information about NRT performance from here:

You can download Solr 3.4 with RankingAlgorithm 1.3 from here:

Please download and give the new version a try.
