Can you please be more explicit to what search box you refer to? To be honest, I don"t understand the report as I am not aware of any "search box". Maybe post a screenshot if in doubt. Thanks!

This one, tested it already and can confirm but didn't find the cause.
I think it's a general nextcloud function that apps need to implement as the search context will switch to the current app.
Searching something while the news app is open will result in a HTTP 405 Error

Exactly, that one. When I use the back button on the error page, the URL bar changes to [Nextcloud path]/apps/news#/items?search=[query] and the results are appropriately filtered.

I did take another look on this.
The cause seems to be a POST that is send by the browser when you hit enter. It simply contains the query. Which leads to a 405. The correct version is handled via a GET.

But my JS-experience is not that great.I guess this could be the default action? And we need to prevent that?
