It most certainly is possible to search by date still.
If you read the solution that so many kind people have posted in here you would see how to use the search box now.
This thread really should be locked now to prevent this kind of repetition.
To save you reading back a few notes, just type something into the search box - I usually use the first letters of what I am looking for or an asterisk if I want to search for "today" or whatever and then hit enter or click the arrow and then the search tab will appear and open up the options to you.
I think everyone is probably hoping that the May 2020 update will put things back how they were - if we ever see it. It seems to have been delayed.
