      Description

      Currently since LUCENE-2236, we can enable Similarity per-field, but in schema.xml there is only a 'global' factory
      for the SimilarityProvider.

      In my opinion this is too low-level because to customize Similarity on a per-field basis, you have to set your own
      CustomSimilarityProvider with <similarity class=.../> and manage the per-field mapping yourself in java code.

      Instead I think it would be better if you just specify the Similarity in the FieldType, like after <analyzer>.

      As far as the example, one idea from LUCENE-1360 was to make a "short_text" or "metadata_text" used by the
      various metadata fields in the example that has better norm quantization for its shortness...
