TODO: Disable "and" or "or" in case it's followed

TODO: Add "and"-method to root to add further constraints
based on match-input (like clicking on a pubDate timestamp in a match)
TODO: Implement "persistence"-Option, injecting the current creation
date stamp
TODO: Implement vec-Type for document-id vectors like docID in [1,2,3,4 ...]
