David Smiley commented on SOLR-1485:
------------------------------------
Just a couple tidbits of feedback on the patch:
* {{computePayloadFactor}} would probably get called a ton of times, thus it's
worth trying to ensure it's implementation is quick. I see you having it doing
"integer" & "float" string comparisons. That can be done beforehand; perhaps
declare a {{java.util.ToDoubleFunction}} initialized with one of 3 lambdas
depending on the situation.
* FloatPayloadValueSource confuses me... ValueSources produce a value _per
document_ yet payloads are _per term *occurrence*_. What use-case do you have
in mind?

> Solr has no support for Lucene's PayloadScoreQuery, yet it has support for
> indexing payloads (via DelimitedPayloadTokenFilter or
> NumericPayloadTokenFilter).
> This issue adds value source and query parser support for leveraging payloads
> created by those token filters.
