Custom score using the max and the min of two fields

Elastic Stack Elasticsearch
1

hi all,

I need to redefine the score in my search result.
The formula I want to use is something like:

"script" : "0.5 * ((doc['priceMin'].value - priceMin) / (priceMax -
priceMin)) + 0.5 *(1 - ((doc['rank'].value - rankMin) / (rankMin -
rankMax)))",
"params" : {
"rankMin" : 1,
"priceMin" : 1,
"rankMax" : 5,
"priceMax" : 130
}

But I want replace the params with calculated value, where rankMin and
priceMin are the min values for related fields in my index, and rankMax and
priceMax are the max values for related fields in my index

Someone know how I can do it?

thanks,
Davide

First you'll need to calculate those values using a statistics facet,
then you can pass them as parameters.

You can't do it all in one request
