This (kinda) works already.
If you type in the search box:
status:noreplies after:2023-01-01
You will get all non-answered topics since 1 Jan '23.
I also played with advanced search UI and if you select 2-3 search criteria they will be added in the order in the search box.
As for the list of all advanced search filters, i am looking after the complete list myself…might post it here when it grows
