[TYPO3-english] Solr faceting and categories: restrict results per (set of) category

[Bert]

Hello,

I have succesfully set up Solr with categories/faceting thanks to this 
article of Steffen Ritter:
http://blog.steffen-ritter.net/2014/04/extsolr-use-categories-as-hierarchical-facets/

However, now I want to restrict the rendering of the results to a 
specific set of categories, depending on the page where the searchbox is 
placed.

How could I restrict the rendering of categories in the case of 
"type=hierarchy")? Please see below for the TS so far (which works fine)...

In which direction should I go:

.facets.queryGroup {

}

.facets.requirements {

}

Other?

Any ideas/pointers? Thanks in advance!

Regards,
Bert
