> Also, what do you mean by scaling continuously? Your algorithm is piecewise vs. continuous. But, I am not sure how we could do a continuous transformation (everything is on the same scale). > I am not too familiar with MBW. Yeah, MBW and MAXSCORE get all mixed up in my brain. But, yes MAXSCORE is why we disallow negative scoring. Forgive my misdirection. > The above formula gives negative and positive scores the same number of possible scores, reducing overall precision by 2 My main concern overall is this: we are changing the scoring methodology period for positive scores (and thus considered "valid"). I think this means that it cannot go into a Lucene 9.x release (correct @jpountz ?). What do you think @msokolov ? Maybe we have a new `MAX_INNER_PRODUCT` scoring that uses @jmazanec15 suggestion? -- This is an automated message from the Apache Git Service.
