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.
