It works great! ... but the &qs doesn't carry over to the next page of
results. So if I want to see more pages, I have to edit the querystring on
each page. Since you already have the inner workings of this in place, it
would be really easy to just add a textbox named "qs" and add the &qs= to
the bottom "5 more, 10 more"... links. With a little more effort, you could
include radio buttons to have the user select how many days, months or years
they want to go back and have your search engine convert it to milliseconds
depending on what the user selects.

If given thousands of results, most search engines have some advanced
options like sorting.

I'd be interested in seeing some statistics on how far the average user goes
when given back let's say 10, 100 and 1,000 pages of results. It would help
in the design of an effective search engine.
