Subject [Announce] Apache Solr 4.0-BETA with RankingAlgorithm 1.4.4 and Realtime NRT available for download
Date Mon, 10 Sep 2012 15:21:04 GMT
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:
http://solr-ra.tgels.org/wiki/en/Near_Real_Time_Search_ver_4.x

You can download Solr 4.0-BETA with RankingAlgorithm 1.4.4 from here:
http://solr-ra.tgels.org

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
