[Announce] Apache Solr 4.6 with RankingAlgorithm 1.5.2 available now with complex-lsa algorithm (simulates human language acquisition and recognition)

Hi!

I am very excited to announce the availability of Solr 4.6 with 
RankingAlgorithm 1.5.2.

Solr 4.6 with RankingAlgorithm 1.5.2 includes the new algorithm 
complex-lsa. complex-lsa simulates human language acquisition and 
recognition (see demo <http://solr-ra.tgels.org/rankingsearchlsa.jsp>) 
and can retrieve semantically related/hidden relationships between 
terms, sentences, paragraphs, chapters, books, images, etc. Three new 
similarities, TERM_SIMILARITY, DOCUMENT_SIMILARITY, 
TERM_DOCUMENT_SIMILARITY enable these with improved precision.

Solr 4.6 with RankingAlgorithm 1.5.2 also includes realtime-search with 
multiple granularities. realtime-search is very fast NRT and allows you 
to not only lookup a document by id but also allows you to search in 
realtime, see http://tgels.org/realtime-nrt.jsp. The update performance 
is about 70,000 docs / sec. The query performance is in ms, allows you 
to  query a 10m wikipedia index (complete index) in <50 ms.

RankingAlgorithm 1.5.2 with complex-lsa supports the entire Lucene Query 
Syntax, ± and/or boolean/dismax/glob/regular 
expression/wildcard/fuzzy/prefix/suffix queries with boosting, etc. and 
is compatible with the new Lucene 4.6 api.

You can get more information about complex-lsa and realtime-search 
performance from here:

ANNOUNCE: Stump The Chump <at> Lucene Revolution EU - Tommorrow


(Note: cross posted announcement, please confine any replies to solr-user)

Hey folks,

On Wednesday, I'll be doing a "Stump The Chump" session at Lucene 
Revolution EU in Dublin Ireland.

   http://lucenerevolution.org/stump-the-chump

If you aren't familiar with "Stump The Chump" it is a Q&A style session
where I (the Chump) get put on the hot seat to answer tough / interesting
/ unusual questions about Lucene & Solr -- live, on stage, in front of
hundreds of people who are laughing at me, with judges who have all seen
and thought about the questions in advance and get to mock me and make me
look bad.

It's really a lot of fun.

Even if you won't be at the conference, you can still participate by
emailing your challenging question to stump <at> lucenerevolution.org.
(Regardless of whether you already found a solution to a tough problem,
you can still submit it and see what kind of creative solution I might
come up with under pressure.)

Prizes will be awarded at the discretion of the judges, and video should
be posted online at some point soon after the con -- more details and
links to videos of past sessions are in my recent blog posts...
