After a search is done you can go page by page thru results. But if you want to go fast by jump to last/first page, the search will be executed without optional search settings.
@psychobunny I believe it has something to do with CentOS or running Plesk/cPanel as I have not for the life of me been able to make it work properly, even with that guide. We are switching to a Debian server soon without Plesk or cPanel so hopefully that will render the issue solved.
