Yes this is the correct path.

After a bit of digging around, it seems that this particular implementation
of the tag cloud relies on Solr as the search back-end. The default for CKAN
(until the next release - 1.5) is to use Postgres full-text
search. (c.facets always comes back empty.)

So I've switched cz.ckan.net to use SOLR and the tag cloud now appears!
