The docBoost, IIRC, is stored in a single byte, which combines the doc

Are the lengths of your documents the same? If not, this could be affecting
your scoring.
You can run luke (http://code.google.com/p/luke/) , and look at the values
for fieldNorm. It's on the documents tab.
There's a little widget in Luke to set the value of norm - just display
the dialog, it shows you the rounding error that this encoding causes
(and what input values effectively come out the same, once encoded).
