Robert Muir resolved LUCENE-2846.
---------------------------------

    Resolution: Fixed

Committed revision 1058367.

I deprecated the dangerous setNorm(float) method in 3.x in revision 1058370,
instead pointing at setNorm(byte) and using Similarity.encodeNormValue(),
so you can ensure your Similarity is always used (not Similarity.getDefault)


> omitTF is viral, but omitNorms is anti-viral.

> omitTF is viral. if you add document 1 with field "foo" as omitTF, then 
> document 2 has field "foo" without omitTF, they are both treated as omitTF.
> but omitNorms is the opposite. if you have a million documents with field 
> "foo" with omitNorms, then you add just one document without omitting norms, 
> now you suddenly have a million 'real norms'.
> I think it would be good for omitNorms to be viral too, just for consistency, 
> and also to prevent huge byte[]'s.
> but another option is to make omitTF anti-viral, which is more "schemaless" i 
> guess.
