We uploaded four separate MBOX files representing 4 email folders into one email archive. Is there a way to do a primary sort by folder to display just the messages from a specified folder, before applying any other filters or facets?
I'm not in a position to test at the moment, but as I recall I managed to do what you've described by first doing a blank search, then faceting by folder. The ability to do that eluded me at first, since I had scroll down to see the folder facet.
Just tested, and this solution works. Thank you!
