Subject [Announce] Solr 3.5 with RankingAlgorithm 1.3, NRT support
Date Tue, 27 Dec 2011 14:32:04 GMT
Hi!

I am very excited to announce the availability of Solr 3.5 with 
RankingAlgorithm 1.3 (NRT support). The performance to add 1 million 
docs in NRT to the MBArtists index with 1 concurrent request thread 
executing *:* is about 5000 docs in 498 ms. The query performance is 
about 168K query requests at 4.2 ms / request.

RankingAlgorithm 1.3 supports the entire Lucene Query Syntax, ± and/or 
boolean queries.
RankingAlgorithm is very fast allows you to  query a 10m wikipedia index 
(complete index) in <50 ms.

You can get more information about NRT performance from here:
http://solr-ra.tgels.org/wiki/en/Near_Real_Time_Search_ver3.x

You can download Solr 3.5 with RankingAlgorithm 1.3 from here:

Please download and give the new version a try.
