Since there are Fastmail people here, I'll say the web app's search is slowly improving, but it leaves a lot be desired. For example, it is stupid around interpreting time intervals for search. E.g., You can ask it to Search "between" times. If you give it __Jan__ and __Feb__, of course, you expect it to include everything between Jan 1 and Feb 28 (if it's not a leap year) or Feb 29 (if it is a leap year). What does it do? after:2023-01-01 before:2023-02-02 Sad.
