Solr Facet Functions and Analytics

Question

I have found the interesting article on Solr Facet Functions available in heliosearch.

I am just wondering if the same is available in native solr?

Answer 1

That kind of functionality will come with SOLR 5.1. Yonik, the developer of Heliosearch, joined a big SOLR company. Development on Heliosearch will not continue, but Yonik is porting the changes to SOLR. See the following thread for details:

Answer 2

I don't think here are facet/aggregate functions like that. The closest thing I've found is the stats component:
