Simply sorting by date doesn't really seem to be that useful either.

For example, the poster below showed the following link for the "ml" query: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que....

If you look at the results, the first 2 results only matched part of the poster's username and many of the top results here are empty threads which are not that useful since HN is mostly for discussions.

To be clear, I'm not saying it's all bad, just pointing out that there are low hanging fruits which can improve results quite a bit.

Also, Algolia seems misspelled in your query which is why it fails when reordering by date: https://imgur.com/a/pO9fBWr, it works otherwise. Although, it says the date is 1 day old when it's just 2 hours old.
