I have been playing with enterprise search and search UI. I use a JSON file to upload the data.
For the values, it looks fine - but for the Keys which are then converted to the names of the facets, I can't use whitespace, special chars like 'ä' etc...
That would kinda limit the use of the facets - What is the correct way to do it?
As for rendering the "correct" keys within Search UI, customizing the code to replace the character-limited field names with their corrected counterparts is likely the best path.
