After a bit of research, following applies:

• /Shared cannot be searched.

GET https://graph.microsoft.com/v1.0/me/drive/sharedWithMe/search(q='Test')
{
    "error": {
        "code": "BadRequest",
        "message": "The request URI is not valid. The segment 'sharedWithMe' must be the last segment in the URI because it is one of the following: $ref, $batch, $count, $value, $metadata, a named media resource, an action, a noncomposable function, an action import, a noncomposable function import, an operation with void return type, or an operation import with void return type.",
    }
}

• Folders added to OneDrive are not searchable
  • Search Results in /My Files/Folder Shared With Me/ will never appear
• Finding files inside a Shared folder must be done while having that folder open
  • Searching in /My Files/Folder Shared With Me will return valid files

Recursive Search for Microsoft Graph (OneDrive, Sharepoint) is disabled in latest release (fe0d6a1), and will be deleted in a future version.
