Tasks

• Improve DX of usage of Facets in search results (make it easy to identify each returned facet, count the results, etc)
• Identify which content / locations properties should support facets, and implement them
• Clear extension point for describing if/how a field type can be facetted. Re-usable tools (abstract classes, etc) that can be leveraged by 3rd party developers
• Extensive documentation about how to use facets, including fields
• Finish support in Solr and ES (EZEE-3152)

Follow-ups

• implement facets in the admin, with default facetting on the most obvious properties: content type, content type group, creation / modification date, section (EZP-31746)
• implement facets in the reusable search controller (EZP-31747)
