A common one I hit is "blu" showing bluetooth settings, but "blue" does not. Very frustrating to see the thing you are hoping for popup, but then go away as you type more if its name.
Android keyboard does that too. When I start typing my email address, for example, the keyboard app suggests the correct email after a few characters, but if I keep typing it disappears from the suggestions.
I have to send a daily email that always has the subject starting with "Work Diary". If I type "W", it doesn't come up. If I type "Wo" it comes up as the 3rd auto-complete suggestion. If I type any more characters, I have to type the entire two words. This is on Android, but I have a feeling it's no better on iOS.
I'd love to know the algorithm they're using for this. Fuzzy search seems like it was a mostly solved problem 20 years ago, and it's definitely worse than it was 10 years ago.
It would be interesting to learn what over engineered solution to fuzzy string matching is being used here to exhibit this behavior, so we never make the same mistake.
Seems like someone got updated KPIs and decided to try the most ham-fisted enshittification move to raise registrations. Oh, it is now possible again to see about five top reviews per item. Seems like loss of traffic was rough.
Just tried this on iOS 27 and both blu and blue showed me bluetooth settings. I saw someone in a different thread of this discussion mention resetting dictionaries helping with autocorrect, I wonder if there is something that would apply to this situation which helps.
