[jira] [Commented] (OAK-5033) JCR Query Row's public getScore() has hardcoded value of 0.01

    [ https://issues.apache.org/jira/browse/OAK-5033?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15615792#comment-15615792 ]

------------------------------------

For specific case of understanding of how scoring is working, check out {{oak:scoreExplanation}} (explained in oak lucene documentation.. I'm currently not in great internet connectivity, else I'd have linked those directly)

>             Project: Jackrabbit Oak
>          Issue Type: Bug
>          Components: lucene
>            Reporter: David Gonzalez
>            Priority: Minor
>
> RowImpl.java [1] hardcodes the result of the public API getScore() to 0.01.
> This is problematic when trying to debug/understand the effects of index boosting on search results. 
> There is documentation that helps illustrate how boosting works wrt to lucene, but it is generally inaccessible to the lay-developer/QA. Understanding how the boost effects the result score would be quite helpful in understanding the effects of boost.
> Note: I understand this does not effect the internal scoring/ordering, however this is a public API and should return the expected value.
