: Fwiw, here's example of per field similarity
: https://cwiki.apache.org/confluence/display/solr/Other+Schema+Elements

Similarities can be defined per field *TYPE* ... not per field (as shown 
in the examples on that page)

I do not think you can specify similarity on a per-field basis like
that.  I think that the similarity must be defined at the top schema
level, and it applies to the entire collection (or core for non-cloud mode).

Thanks,

Hi,

Sweet spot is designed to punish too long or too short documents.

Did you reindex?

Can you see the mention of sweet spot in debugQuery=true response?
