I see. It appears the key "Content Type" is indexed as "ContentType",
so searching for "ContentType:*" (without quotation marks) will work.

Hint: Looking at the Solr admin-interface at localhost:8983 of dev
machine helps figuring out stuff like that.

I see. So but that works, at least with CKAN 2.8.2 and default SOLR
schema.

A for the other task, getting dynamically created extra fields
dynamically into facets, I don't know how to do that. Can imagine
that gets tricky.
