Bug description

When searching for a file, that is present inside subfolder, I received 207 response with "no search file found" (in French, exactly: Aucun résultat de recherche pour )

Which is strange, because I know the file is present inside a folder.

I have checked some file can be found, but not all

Steps to reproduce

1. Click on the "search input" on the top left
2. Write the name of a file
3. Search everywhere

Sometimes it works, sometimes not.
...

Expected behavior

It should find existing file :-)

Additional info

No response

Start by reproducing the search from the top-left input with files in subfolders, comparing files that are found with those that are missed on Server 32.0.5 and Desktop Client 32.0.5. Inspect the available Nextcloud Server logs and account for encryption and the external user backend; done means every existing file is returned consistently.
