The ScoresAsPercentages page is not really instructions for how to normalize scores. It is an explanation of why a score threshold does not do what you want.

Those generally give worse results than a vector space model, but you can have thresholds. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Jan 20, 2016, at 5:11 AM, Emir Arnautovic <emir.arnauto...@sematext.com> > wrote: > > Hi Sara, > You can use funct and frange to achive needed, but note that scores are not > normalized meaning score 8 does not mean it is good match - it is just best > match.
