Hi!

I am very excited to announce the availability of Solr 4.0-ALPHA with 
RankingAlgorithm 1.4.4 with Realtime NRT. The Realtime NRT 
implementation now supports both RankingAlgorithm and Lucene. Realtime 
NRT is a high performance and more granular NRT implementation as to 
soft commit. The update performance is about 70,000 documents / sec*. 
You can also scale up to 2 billion documents* in a single core, and 
query half a billion documents index in ms**.

RankingAlgorithm 1.4.4 supports the entire Lucene Query Syntax, ± and/or 
boolean queries and is compatible with the new Lucene 4.0-ALPHA api.

You can get more information about Solr 4.0-ALPHA with RankingAlgorithm 
1.4.4 Realtime performance from here:

You can download Solr 4.0-ALPHA with RankingAlgorithm 1.4.4 from here:
