Subject [Announce] Apache Solr 4.0 with RankingAlgorithm 1.4.4 and Realtime NRT available for download
Date Mon, 29 Oct 2012 14:06:30 GMT
Hi!

I am very excited to announce the availability of Apache Solr 4.0 with 
RankingAlgorithm 1.4.4 and Realtime NRT. 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 is different from realtime-get. realtime-get 
does not have search capability and is a lookup by id. Realtime NRT 
allows full search, see here <http://solr-ra.tgels.org/realtime-nrt.jsp> 
for more info.

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/dismax/boost queries and is compatible with the new Lucene 4.0 api.

You can get more information about Solr 4.0 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 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 with RankingAlgorithm 1.4.4 is an external project

* performance is a real use case of Apache Solr with RankingAlgorithm as 
seen at a user installation
** performance seen when using the age feature
