How to mass delete (purge) the archive?

[quantissimo]

I archived an email box together with a 10000 spam emails. How to delete them in bulk?

I am also facing the problem. Most emails are garbage and I want to search but I get thousands of results with just 1 big result listed because the same term shows up hundreds of times in that one result. but then there is no way to even delete that one result right away. instead you have to click that one result, land on the next page, then click delete. that sends you to not the search results page so then you have to navigate back to the results page and hit results again to be able to see a new email that you want to delete. Its impractical to clean up the emails that way.
