With a Hits, if the top score is greater than 1.0 then all scores are 
divided by the top score.  This is just a cheap hack to mollify folks 
who are alarmed when scores are greater than 1.0.

Lucene scores are not designed to have much meaning beyond the relative 
ordering they provide.  For example, if you wish to meaningfully 
eliminate hits beneath some particular score then you might need to use 
a more elaborate normalization or choose a different threshold score for 
each query, or something like that.
