Shame on Yandex for his search for letters in the mail interface

There is something to compare with - for some reason, everything is quickly located in Gmail, there are parameters - from whom, to whom, etc. You can search in Yandex.Mail only by folders, there are no other parameters, I personally don’t find a letter, although I I know for sure that they are there. By the way, this is not the first time I've come across, is nobody really looking for anything else in their Yandex.Mail?
