User Story:: As a user, I want to have helpful search fields in the form so I can find what I'm looking for with a high likelihood.
Context of use: I assume the user would like the provided fields to behave in a predictable way.
Current Problems: Currently, this field doesn't exist at all because it didn't make sense to add it with the "prefix" keyword because of the current discrepancy it caused.
Possible Solution: One way to improve the situation for the user is to have another keyword which was implemented called "subpageOf" T159321. To be able to use this in the form though the UX-Team first needs to understand exactly how it works.
