Subject [jira] Updated: (LUCENE-557) search vs explain - score discrepancies
Date Mon, 01 May 2006 22:52:46 GMT
     [ http://issues.apache.org/jira/browse/LUCENE-557?page=all ]

Hoss Man updated LUCENE-557:
----------------------------

    Attachment: LUCENE-557-newtests.zip

Some new tests covering every type of query in the "core" lucene code base.  various examples
of each query type are checked both that explanations for "matching" docs have the correct
value, and that "non-matches" have an explain vlaue of 0.0.

some of these tests may not be considered "fair" since the use boosts of 0.0 (and cause scores
of NaN) but I was trying to be as complete as possible.  As is there are many seemingly legitimate
queries in here whose explanations are totally bogus.

(NOTE: classes in Zip depend on previously attached PATCH)

> I'm on a mission to demonstrate (and then hopefully fix) any inconsistencies between
the score you get for a doc when executing a search, and the score you get when asking for
an explanation of the query for that doc.
