I've never had the feeling that it was particularly bad. In your case it seems to be that the game Night Run was removed from the Steam Store, which is why it's excluded from the search. Which isn't great when the store page still exists...
Yeah, I’ve noticed this happens when steam removes a game. They need to do a Netflix sort of thing and be like “We know this exists, but we don’t have it”
i hate how you can only filter price by 5's, so if you have like 17 bucks in your steam wallet you have to sort by 20 and ignore like half of the options
