realtime comes from the tag used to enable the functionality in
solrconfig.xml. nrt is used as an acronym as in radar/laser/jpeg/cdrom,
etc. nrt is so well known I did not expect it to be expanded to its full
form which does make it oxymoronic ...

It certainly seems to be a rogue project, but I can't understand the
meaning of "realtime near realtime (NRT)" either. At best, its
oxymoronic.

Could any of the committers here confirm whether this is a legitimate
effort? I mean, how could anything labeled "Apache ABC with XYZ" be
an "external project" and be sanctioned/licensed by Apache? In fact,
the linked web page doesn't even acknowledge the ownership of the
Apache trademarks or ASL. And the term "Realtime NRT" is nonsensical.
Even worse: "Realtime NRT makes available a near realtime view".
Equally nonsensical. Who knows, maybe it is legit, but it sure comes
across as a scam/spam.

Subject: [Announce] Apache Solr 4.0 with RankingAlgorithm 1.4.4 and
Realtime NRT available for download
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
