So I’ve had this problem ever since the search feature launched, but I hoped it would get better with time. Sadly it hasn’t.
Search just doesn’t work for some feeds. Take https://yts.to/rss/0/1080p/All/0 for example. Any search request I make, no stories will show up, even though I am writing a word from on of the story titles.
And when search actually works, it shows results for read stories as well as unread, even though I have the feed set to only show unread stories. It would be nice if search actually respected this setting.
I’m going to start with saying that this post is “severely” mis-named. Your issue is that it doesn’t work on a feed. That doesn’t make it severely broken.
As for not respecting Unread when searching, that’s deliberate, as you’re searching for a story.
I haven’t looked at the feed, but I assume it’s got non-ascii characters. Try insta-fetching it.
Sorry for the wrongly named title. It just feels broken to me, because it rarely behaves how I expect.
The feed I linked doesn’t contain any special characters as far as I can see. And I can see all the stories, but when doing a search, nothing comes up.
As for the search behavior, it would be nice for a settings toggle between searching everything and just unread. I mostly use the search function as a filter, to quickly filter out any unread stories containing my search term.
