--------------------------------------------------------------
It's interesting to note that there is actually one query built in that could
handle payload scoring already: {{q=\{!xmlparser}<BoostingTermQuery
fieldName="weighted_terms_dpf">weighted</BoostingTermQuery>}}, with hardcoded
"average" function and includeSpanScore=true, resulting in the above data
example an output of:
{code}
id,score
2,71.00154
{code}
And here's a patch that adds includeSpanScore control flexibility to
{{<BoostingTermQuery>}}:

> 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.
