From a user perspective, this would indeed seem like a bug. In the backend, the Parser in the backend likely interprets this as a generic KEYWORD and not a flag. Possibly solution could be to rework the Parser to detect [letter]/ as a flag, but not sure how much work that is.

Also have to consider that people could legitimately have p/123028 be their name nowadays, in which case that would be a valid search.
