Search SMB Folder on Android App

Hey Guys,
I have a problem with the research on android Nextcloud App.
On Chrome, If in the search field I type to search for an SMB folder, I can view it.
In Android, if I try to search for the folder, the name of the SMB folder does not find, but at most it finds , if the word is also contained in the file, the file (s) contained in the SMB folder.

What can i do for this problem?

Thank you so much
