Scoring of a rep:similar search is not as expected
--------------------------------------------------

                 Key: JCR-1945
                 URL: https://issues.apache.org/jira/browse/JCR-1945
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core, query
            Reporter: Alexander Klimetschek
            Priority: Minor


A normal rep:similar query, such as

    //element(*, nt:hierarchyNode)[rep:similar(jcr:content, 
'/content/some/path/jcr:content')]

will return a properly ordered result, with the most similar nodes at the top. 
However, adding an order by @jcr:score

    //element(*, nt:hierarchyNode)[rep:similar(jcr:content, 
'/content/some/path/jcr:content')] order by @jcr:score desc

will return a list with not-so-well-matching nodes at the top. I think one 
would expect the score value to depend on the similarity, ie. the more similar, 
the higher the score, so the result should look just as the one without an 
order by.

(tested only on a Jackrabbit 1.4.6)
