FileAPI, find method doesn't work well for Group Folders

Describe the bug

When the search target is a Group Folder, if the path contains only the root folder, the Find method works great. I can get all matching files, even in deep subfolders. But if the path contains a subfolder, the search result is empty.

When the search target is other than a Group Folder (personal folder or shared folder), it works great with paths containing subfolders.

Steps/Code to Reproduce

1. nc.files.find(["like","name","%.png"],path="GroupFolderB/")

2. nc.files.find(["like","name","%.png"],path="GroupFolderB/subFolderA")

Expected Results

Returns matching files under the target path (including subfolders)

Actual Results

Returns empty results.

Do you know if this is perhaps by design or are you sure PROPFIND is supposed to work with subfolders in Groupdolders?

[zhongzishi]

PROPFIND works with subfolders in Groupfolder, here is an example with NC webDAV api:

import requests
from requests.auth import HTTPBasicAuth
import xml.etree.ElementTree as ET

def get_files_in_folder(url, auth, headers):
    data = '''<?xml version="1.0"?>
    <d:propfind xmlns:d="DAV:">
      <d:prop>
        <d:resourcetype/>
        <d:displayname/>
        <d:getcontentlength/>
        <d:getlastmodified/>
      </d:prop>
    </d:propfind>'''

    response = requests.request("PROPFIND", url, headers=headers, data=data, auth=auth)
    response.raise_for_status()
    return response.text

def parse_response(response_text):
    root = ET.fromstring(response_text)
    items = []

    for response in root.findall('{DAV:}response'):
        href = response.find('{DAV:}href').text
        displayname = response.find('.//{DAV:}displayname').text
        resourcetype = response.find('.//{DAV:}resourcetype/{DAV:}collection')
        contentlength = response.find('.//{DAV:}getcontentlength')
        lastmodified = response.find('.//{DAV:}getlastmodified').text if response.find('.//{DAV:}getlastmodified') is not None else None

        items.append({
            'href': href,
            'displayname': displayname,
            'is_dir': resourcetype is not None,
            'contentlength': contentlength.text if contentlength is not None else None,
            'lastmodified': lastmodified
        })

    return items

folder_url = "https://example.nextcould.com/remote.php/dav/files/userA/GroupFolderB/subFolderA"
auth = HTTPBasicAuth(NEXTCLOUD_USERNAME, NEXTCLOUD_PASSWORD)
headers = {
    "Depth": "1",
    "Content-Type": "application/xml",
    "Accept": "application/json"
}

response_text = get_files_in_folder(folder_url, auth, headers)
files = parse_response(response_text)

for file in files:
    print(f"Name: {file['displayname']}, Size: {file['contentlength']}, Last Modified: {file['lastmodified']}, Path: {file['href']}")

And I'm able to get files/subfolders under this group folder.

response = requests.request("PROPFIND", url, headers=headers, data=data, auth=auth)

Unfortunately, it is a PROPFIND request, and not SEARCH

I found such issue:

https://github.com/nextcloud/groupfolders/issues/2583

Looking at code, I do not see a handler for SEARCH requests:
