* The function is overridden because the current VF2 implementation does'nt take care (22.12.2014) about the number of facets shown for each category.
* It always displays a fix number (at the moment five items defined in the Recommend\SideFacets.phtml)
* Because we implemented a more flexible definition for Solr it has to be changed somehow for Summon too. I guess this is matter of change in the future by VuFind
* so I don't invest too much into it
