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

Hi Nagendra,
really cool topic.
I'm really interested in discover more information about the three
similraties algorithm you offer ( Term Similarity, Document Similiraty and
Term In Document Similarity).
I was looking for more details and explanations behind your Ranking
Algorithm.
Where could i start ? I'm really curious of the LSA Model used and also low
level algorithm and science applied.
Good work !

Cheers
