Subject [jira] [Commented] (OAK-3352) Expose Lucene search score explanation
Date Mon, 07 Sep 2015 07:40:45 GMT

    [ https://issues.apache.org/jira/browse/OAK-3352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14733344#comment-14733344
] 

Chetan Mehrotra commented on OAK-3352:
--------------------------------------

bq. Can't we use the explain query support for this purpose?

[~amitj_76] explain support cannot be used as it does not compute actual result. The score
is on per result row basis so we need to make it part of the result row

> Lucene provides {{Explanation}} [1] support to understand how the score for a particular
search result is determined. To enable users to reason out about fulltext search results in
Oak we should expose this information as part of query result
