Indexing of dataflows in sub-categories misses adding the sub-category to the categoryscheme facet
Dataflows categorised in sub-categories cannot be found through navigating through the related categoryscheme facet, but should, when dataflows are indexed using the sfs /admin/dataflows method (note that those dataflows have been deleted previously to trigger their complete/fresh re-indexing).
Example: All dataflows categorised in category "IND.IND_TOUR" (which is a sub-category of "IND") in the categoryscheme http://nsi-stable-siscc.redpelicans.com/rest/categoryscheme/OECD/OECDCS1/1.0. These dataflows can be retrieved through http://nsi-stable-siscc.redpelicans.com/rest/categoryscheme/OECD/OECDCS1/1.0/IND.IND_TOUR?references=dataflow, and they should all be findable through the "Topic" facet value "Industry / Tourism" below the value "Industry", which is currently wrongly not available:
