Bug description

Setting a date filter in unified search does not work for files

Steps to reproduce

(See #52081 (comment) for more details)

1. Open unified search
2. Manually set a date filter (e.g. 01.01.25 - 02.02.25)
3. Search for something

Expected behavior

Only files within the set filter should be shown.

Nextcloud Server version

master

I am not sure if that is supposed to work (= bug) or if it's not supposed to work anyway (= feature request)?!

UX wise definitely a bug if it is not supported we should not offer the option.

[SystemKeeper]

if it is not supported we should not offer the option.

Indeed, but I think the issue might be that only some search providers might support it?

[SystemKeeper]

Hm, from the code it seems that since should be supported in general:

server/apps/files/lib/Search/FilesSearchProvider.php

Line 75 in 319216c

'since',

server/apps/files/lib/Search/FilesSearchProvider.php

Line 144 in 319216c

'since' => new SearchComparison(ISearchComparison::COMPARE_GREATER_THAN_EQUAL, 'mtime', $filter->get()->getTimestamp()),

...

It seems that the search provider for the current folder does not have the since properties attached to the query, but manually selecting only files seems to work for me. I'll take a closer look, maybe it's a misunderstanding on my side.

After some further tests, it seems to have something to do with "Load more results":

Working:

• Go to files and reload the page
• Open unified search, select "Files" as filter and add a custom date range
• Then enter the search query
  -> Works fine

Non-working:

• Go to files and reload the page
• Open unified search, select "Files" as filter
• Search for something, click on "Load more results"
• Now add a custom date range
  -> Anything that is now searched, does not obey the date filter, but the filter is still visible in the UI

Side-effect:

• Go to files and reload the page
• Open unified search, select "Files" as a filter and add a custom date range
• Then enter the search query
• Now pressing "Load more results" does immediately remove the filter from the UI
  -> Also feels like a bug to me, but at least the state is correctly reflected in the UI
