> norm compression breaks ranking for small fields

>                 Key: LUCENE-517
>                 URL: https://issues.apache.org/jira/browse/LUCENE-517
>             Project: Lucene - Java
>          Issue Type: Bug
>          Components: Index, Search
>    Affects Versions: 1.9
>         Environment: N/A
>            Reporter: Randy Puttick
>            Priority: Minor
>
> The scheme of compressing document norms to one byte loses a lot of 
> information.  This completely breaks search ranking on small fields because 
> there is no way to see the difference between documents with shorter and 
> longer fields that contain the same number of matching query terms.  
> Unfortunately the export of norms as a byte array seems to be pretty well 
> embedded in the code base so a fix would seem to require a major rev.
