----------------------------------------
Once I can get past the hurdles of creating my first patch from the git mirror,
I'll upload it.
> 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
> Labels: newdev, patch
> 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}
