hi,

I have K numerical fields

1. Currently for each field I have a script score computing a normalized  
score [0,1] representing linear decay inside a range. like :

script\_score: " clamped\_value = max(min(doc['field\_i'].value),max\_value,  
min\_value); return (clamped\_value - min)/(max-min)"

I would like to aggregate all these scores with different weights to get a  
global _normalized score_ like:

either a weighted mean / linear combinaison e.g. global\_score = sum  
(score\_field\_i \* weight\_field\_i) / sum(weight\_field\_i)  
or a harmonic mean

How to do that? Do I have to implement a specific scorer , if yes, is there  
any code example

1. I would like to keep these subscores to display then in the results for  
each doc or even play with facets..

How to do that?

Thanks
