Payload scoring in elasticsearch?

[pauloamed (PAULO MEDEIROS)]

Hey!

I've been trying to write a custom text scoring function in Elasticsearch and I can't find a way to do it. I want to weight the score of each query term with a payload passed inside the query. How can I do it using elastichsearch?

There are similar posts to this, but neither of them with answers:

Payload Scoring in ElasticSearch

Solr has specific feature to allow scoring based on payload - {!payload_score f=payload_field func=sum operator=or}A B C https://lucene.apache.org/solr/guide/7_1/other-parsers.html#payload-score-parser Is there any similar functionality in ES, which can allow scoring based on terms in payload field and , score can be a sum of payloads.

Using payloads for scoring

I am working on a research project in which I need to use some specific term weights for relevance score calculation. I have indexed the term weights as payloads along with the text and looks something like this : "Americans|5.432 to|0.000 rate|5.466 their|6.080 ideology|3.303 on|0.000 a|0.000 liberal-to-conservative|0.000 scale|3.455 of|0.000 1|0.000 to|0.000 5.|0.000 The|0.000 average|5.201 " Now, I want to use these term weights in the relevance score calculation. I was searching for it and…

Is it an open issue?

Cheers,
Paulo

Hi,

It is a bit more complex than weight terms by payload, Function score does not help you?
