I recently started using the relevanssi search for my admin interface, and although the search works great it seems to no longer allow my editors to sort their results by title or date.
after search results are returned my editors frequently need to further refine the search results by sorting by title or date. Traditionally, clicking the "Title" or "Date" column header will do this. But with relevanssi search enabled in the admin interface, clicking either of these column headers reload the page but does not change the results.
Here's a sample of the URL for "title": edit.php?s=my+search&post_status=all&post_type=post&action=-1&m=0&cat=0&mode=list&action2=-1&orderby=title&order=asc
