Trying to google a claim someone made, I found myself looking for something a couple months back. But if I were to search today, a more current would've taken over search results.
So I used the date filter, and yet articles are still labelled "today" and other recenty amounts.

I tried several times, by typing, by using the little popup calendar , double checking it, using enter vs clicking the button. But it just didn't work
When specifying an older date range, I expect older articles. I know that can be impossible for some content, but I do expect content labelled "Today" when explicitly filtering for not-today not to be there
