In Oldnews
Clicking "Publication year" in the top three triggers a numeric keyboard, at least on my tablet,
And one is only allowed to enter a "1" or "2" as the first character, can only enter digits, can only enter at most 4 digits.
Clicking in "Publication year" in the top three also causes a line below to appear "Match year flexibly" with a little down arrowhead after it.
Clicking that line gets a choice of
Match year exactly
+ / - 2 years
+ / - 10 years
+ / - 20 years

So one is able to choose something in the way of a range, but limited choices.
Or in "Publication date" in Filters one can enter an exact date.

On Newspapers.com
one can enter a year, a month year, a month date year,, Or a Range in the Date field (in the top three fields)
