I feel like I also learned the other day that Google’s search is bad like this too. That it’ll say there’s millions of results and just stop after like 400.
An unqualified search reports (at this writing) just north of 30 million results (30,000,229). It will display only 34 pages' worth of results, I believe 1,000.

As discussed recently on HN, the match count is useful information even where all matching results are not displayed as it indicates whether or not a query is generic.
Contrast search: <https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...> (one result as of this writing).
