@Erik: I didn't know that, how can I figure out which query types support payload scoring? The class I described is wrapped into an elasticsearch plugin so I don't have full control over this. Currently I'm using the SpanTermQuery, maybe another available query type will do, so I don't need to implement a custom query parser as well. Thank you!
@Michael: This was my first thought as well but I couldn't find any resources when I first searched for it. I just discovered LUCENE-7854 <https://issues.apache.org/jira/browse/LUCENE-7854>, the DelimitedTermFrequencyTokenFilter, but it can't handle floating values right?
