Search within folder (iOS)?

In the iOS app, the search feature seems to include all files.

I have a user with many files of similar names and they want to find one in a specific folder, but they can’t seem to search just that folder in the iOS app — they are inundated with irrelevant hits from folders other than the one they are looking at.

Is there any way to limit the scope of the search — to make it work more like the way the web client does?
