> search in Proton Mail is so bad I couldn’t use it for even simple things like finding my airline tickets.
Not sure if it's related but
Proton does not hold your unencrypted email body content
consequently only you do once you are logged in. Thus you can't have server side search on your email content, only on email title. What you can have though is client side full-text search on body content. For that you have to enable it via the search box, details https://proton.me/support/search-message-content
It's not perfect but obviously it's a LOT more than searching only on titles.
Protons email encryption is mostly snakeoil and marketing. Their guarantees of strict encryption at rest is really only relevant to a certain class of people with a very specific threat model. Everyone else that uses the service is just leaking plain text email with everyone they converse with who uses a service that does not offer the same encryption guarantees.
So basically they sacrifice a usable search function for a security service that isn't relevant to 99% of people and isn't even effective half the time.
Yeah I tried it and it was still unusable. I barely noticed any improvement.
