             Summary: some improvements about the latent semantic search, more details are
in Description part
                 Key: LUCENE-4458
                 URL: https://issues.apache.org/jira/browse/LUCENE-4458
             Project: Lucene - Core
          Issue Type: Improvement
          Components: core/query/scoring
            Reporter: wang jianping


Hi,all,Recently I invented a new ranking algorithm inspired by the theory of spread activation
and probabilistic model, which can find the latent semantic relationship between docs and
terms and is almost linear time, and I took one afternoon to code and implement this algorithm.
And the testing result shows that the speed of this algorithm is much faster than the famous
Latent Semantic Analysis algorithm, and the affect is almost as good as the LSA. I wanna share
my idea to all of you and add this algorithm to the Lucene project.
