Hi!
I am very excited to announce the availability of Apache Solr 4.0-BETA
with RankingAlgorithm 1.4.4 and 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*
(almost 1.5-2x performance improvement over soft-commit). You can also
scale up to 2 billion documents* in a single core, and query half a
billion documents index in ms**.
Realtime NRT has been contributed back to Solr, see JIRA:
https://issues.apache.org/jira/browse/SOLR-3816
RankingAlgorithm 1.4.4 supports the entire Lucene Query Syntax, ± and/or
boolean queries and is compatible with the new Lucene 4.0-BETA api.
You can get more information about Solr 4.0-BETA with RankingAlgorithm
1.4.4 and Realtime NRT performance from here:

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

Please download and give the new version a try.
Note:
1. Apache Solr 4.0-BETA with RankingAlgorithm 1.4.4 is an external project
