I have found a way to make Piwik track the facets - it's a workaround
but it shows you how often each facet-field is used:
Piwik has a "Goal-Module", there you can define a goal, for example, by
the text of the URL (e.g. &filter=language). Piwik makes a count for a
goal each time a link with the defined text is clicked.
