public/extendable
Markus Jelsma created SOLR-8673:
-----------------------------------
Summary: o.a.s.search.facet classes not public/extendable
Key: SOLR-8673
URL: https://issues.apache.org/jira/browse/SOLR-8673
Project: Solr
Issue Type: Improvement
Affects Versions: 5.4.1
Reporter: Markus Jelsma
Fix For: 5.5, master
It is not easy to create a custom JSON facet function. A simple function based on AvgAgg quickly results in the following compilation failures:
