--------------------------------------
Summary: The PayloadTermWeight explanation hides the details of
the payload score
Key: LUCENE-4249
URL: https://issues.apache.org/jira/browse/LUCENE-4249
Project: Lucene - Core
Issue Type: Improvement
Components: core/search
Affects Versions: 4.0-ALPHA
Reporter: Scott Smerchek
Priority: Trivial
Fix For: 4.0
I'm using the PayloadTermQuery and scoring documents using a custom algorithm
based on the payloads of the matching terms. The algorithm is implemented in
the custom PayloadFunction and I have added an Override for the explain.
However, the PayloadTermWeight explanation hides the details of the payload
score...
{code}
Explanation payloadExpl = new Explanation(scorer.getPayloadScore(),
"scorePayload(...)");
{code}
This is different than the way that PayloadNearSpanWeight explains the payload.
It actually asks the payload function for the explanation rather than hiding it:
{code}
Explanation payloadExpl = function.explain(doc, scorer.payloadsSeen,
scorer.payloadScore);
{code}
