Sort by date ascending and date descending in article search

[rhb123]

Would it be possible to get a sort by 'Date - Newest' and 'Date - Oldest' in the filter box on the article search page at https://olh.openlibhums.org/articles/ please? The options are currently 'Show' (and then number of articles) and 'Sort' with the option to sort by date or title, so the option to choose from date ascending or descending to sort articles would be good so that you can start with the oldest articles if needed. Thanks for your help.
