MAXNORMALIZE
Name
MAXNORMALIZE
Synopsis
Recomputes all hits for a term or subquery so that their weights fall between 0-1.
Arguments
Term or Subquery
Ranking Scheme
weight = weight / maximum weight The weights are recalculated by dividing each hit's weight by the largest weight found in the list of hits for the term.
Comments
MAXNORMALIZE is designed to help you put weights between 0 and 1. Typically this is done as the last step of your query when you have used weights that were larger than 1. This can occur when biasing terms to make them more relevant than terms which already had a weight of 1.
MAXNORMALIZE simply "stretches" the hits so that they span between 0 and 1. This isn't usually the most effective way of normalizing your weights. We suggest you use NORMALIZE instead as it typically more accurately deals with the data.
Example
MAXNORMALIZE( 'blue' );
