[Announce] Solr-RA, Solr with RankingAlgorithm

[Nagendra Nagarajayya <nn...@transaxtions.com>]

Hi!

I would like to announce Solr-RA, Solr with RankingAlgorithm. Solr-RA 
uses the RankingAlgorithm, a new scoring and ranking algorithm instead 
of Lucene to rank the searches. Solr with RA seems to enable Solr 
searches to be comparable to Google site search results, and much better 
than Lucene (perl index). RankingAlgorithm still uses the Lucene index 
to read documents but ranks and scores on its own. There is no change to 
the existing Solr setup, so searches, faceting, highlighting, etc. 
should work as before.

You can get more information about Solr-RA from here: 
http://solr-ra.tgels.com <http://solr-ra.tgels.com/>

You can find the comparison paper between Google site search and Lucene 
here: 
/http://solr-ra.tgels.com/docs/TestWithPerlOrgComparisonWithGoogleAndLucene.pdf/

You can try out a demo (search Wikipedia, Perl/Php/Python indexes) here: 
http://solr-ra.tgels.com/rankingsearch.jsp

Solr-RA has two modes, a Product mode and a Document mode for document 
searches. Document mode is for searching html, rich text (pdf/word, 
etc.), books, faq, forums, etc. while Product mode is for short text 
searches as in retail stores, ecommerce, etc.

You can download Solr-RA from here: http://solr-ra.tgels.com

You can download RankingAlgorithm from here:

I would like you to try it (it is free) and provide us your valuable 
feedback. You can contact me at solr-ra at tgels.com or at the above 
email address or on twitter @solr_ra.
