Hi

I have a noobie question. I am trying to use the SweetSpotSimilarity (SSS) 
class.

http://lucene.apache.org/core/old_versioned_docs/versions/3_5_0/api/contrib-misc/org/apache/lucene/misc/SweetSpotSimilarity.html

I understand the scoring behavior of Lucene

http://lucene.apache.org/core/old_versioned_docs/versions/3_5_0/api/all/org/apache/lucene/search/Similarity.html

And I am aware that SweetSpotSimilarity resulted from this paper

http://trec.nist.gov/pubs/trec16/papers/ibm-haifa.mq.final.pdf

However, I was wondering if there was a resource that explained (and gave 
examples) of how SSS works and what each parameter (hyperbolic, etc) means. I 
know this is a Lucene list but I am actually trying to use SSS in solr. I am 
aware of SOLR-1365 patch that makes configuring SSS easier (in the schema.xml) 

https://issues.apache.org/jira/browse/SOLR-1365

but I am having trouble understanding what some of the 13 parameters are and 
how they map to SSS. 

Thank you

Peyman
