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:

You can download Solr 4.0 with RankingAlgorithm 1.4.4 from here:

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