Why Last Year's top links search provides only 34 pages?

I annually gaze up the top links on HN to improve myself. Last year it returned 50 pages (I suppose). Today https://hn.algolia.com/?dateRange=pastYear&page=49&prefix=false&query=&sort=byPopularity&type=story link returns "We found no stories matching your query for this period." Is there anyone who can list top 50 pages? @dang could you provide them in an article? Thanks in advance.
