Remember that the norm is a product of the length norm and the index
time boost... it
I've done some testing with the example docs and it behaves similar when there
is a zero doc boost. Luke, however, does not show me the index-time boosts.
Bost document and field boosts are not visible in Luke's output. I've changed
doc boost and field boosts for the mp500.xml document but all i

Because the index-time boost was set to 0 when the doc was indexed. I
can't say how that happened... look to your indexing code.

Hi,
I've worked around the issue by setting omitNorms=true on the title field. Now
all fieldNorm values are 1.0f and therefore do not mess up my scores anymore.
This, of course, is hardly a solution even though i currently do not use
index-time boosts on any field.
The question remains, why do

Of course, you're right. The E-# got twisted in my mind and became negative.
Silly me.

Regarding "Negative or zero value for fieldNorm", I don't see any
negative fieldNorms here... just very small positive ones?
Anyway the fieldNorm is the product of the lengthNorm and the
index-time boost of the field (which is itself the product of the
index time boost on the document and the inde
