I've used it a thousand times.
google book search
Search tools--> Any time --> Custom range
Today I was looking in google books for "yahweh" in books ...
(trying to find out the first usages of this name, with the precise spelling)
I also tried "heavenly witnesses" (a search I have done many times).
When I place all the books in the search it comes up fine:
36,500 for "yahweh"
791 for "heavenly witnesses"
Then I was limiting the dates ... and generally the books did not come up.
Please, one or two .. try it and let me know if it works for you.
e.g. put in 19th century ... or put in 1500 to 1990.
Temporarily I could use "sort by date" for a fakeout but that would require navigating to the last page.
There is a "reset search tools" but that will undo the date.
This is puzzling since I have used these date searches for years.
Yes I tried a second browser (Firefox and Chrome) and I used the "reset" and then a redo of the date.
