Hi, Is there a way to normalize the value of fieldValueFeature and OriginalScoreFeature features within some range i.e 0-1.
Lets suppose I have 4 products with some field values, I wish to normalize weight within 0 and 1 using func (val-min)/(max-min). Product FieldValue Normalized Value P1 4 1 P2 3 0.6 P3 2 0.3 P4 1 0 P5 - -1 If the product does not contain the field value, make feature value as -1 (some static). I tried to use the scale function, but since scale function works on the whole index, so it will not be relevant for our case. If you multiple function here, performance will be impacted. I have seen solr ltr source code and there is a normalized function, but not sure how to implement it in our case. Regards Kamal
