I wonder what they mean by "oldest entries" after doing a query for "Apple II". The first two results were this day in history style pages, with the first page having a publication date in 2019. The third pointed to a Wikipedia article, and the next two pointed to abstracts of articles published in the years following the introduction of the Apple II (which I suppose is valid, even though it wasn't what I was expecting).

In order to be a meaningful tool, there needs to be a meaningful definition of oldest entries. Pulling up pages with accurate dates, such as the abstracts, or even when the pages were originally indexed would be far more useful. (Since I am assuming that it is next to impossible to ascertain when content was actually posted.)
