Subject [jira] [Commented] (OAK-3352) Expose Lucene search score explanation
Date Mon, 07 Sep 2015 12:51:46 GMT

    [ https://issues.apache.org/jira/browse/OAK-3352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14733654#comment-14733654

Davide Giannella commented on OAK-3352:
---------------------------------------

I see it as a debug feature too, or at lease that will be used mainly
for debug or performance analysis. On the other hand I don't like
exposing yet another configuration feature as it could be easily be
forgotten in the index definition and slowing down.

I like to column approach as it makes it easy to extract the query you
want to analyse and bump it in any query tool looking then for the
output.

> 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
