I have content type where tagged persons names are automatically saved as a taxonomy term. These created terms have a field, which is a field collection of a date and another taxonomy term which keeps information about the unit. What I'm trying to achieve is, to search for nodes via the unit taxonomy term which will bring up nodes where persons from this unit are tagged. I have no clue how to get it work. I guess somewhere under relationships or contextual filters should be the options but so far I wasn't able to figure it out.
Person (taxonomy term)
- date / unit (taxonomy term in a field collection field of taxonomy term above)
