Feedback Search only under folder (2021.1)

Say I want to upgrade a hundred materials under a specific folder to URP from standard which I got from an old project and it has a very complex folder structure. Like 3-4 levels of different folders under different folders. But also, I already have another hundred materials in my entire project spread across different folder structures. Basically what I want to do is 'Show all materials under this folder, recursively'.

Before 2021, when I used 'Search by Type', I could check Material and click 'in Folder' to see the materials in/under that folder recursively. But that does not seem to be the case with 2021 as the search window is now supposed to be a bit more elegant and elevated. Well... it seems not?

Can't search by type, shows no results. Can't search folder-specific. Any reason behind the logic? Or am I missing something?

Thanks in advance.
