Modifications to Search page

[tomshawk]

If possible, I would like to see a few modifications to the search function.

I have Articles, Questions of the week, Yada Yada

And I would like to either modify the search.php or create a new file (call it latestposts.php or some such), which ever is easier and have variables set up.

One variable would be for lets say all post within the last 7 days or so
One Variable that acts like the search.php?do=getnew
One that acts like the search.php?do=getdaily
One that looks like search.php?do=QOTW that only pulls from my QOTW forums
One that looks like search.php?do=articles that only pulls from my Articles forums

Any help with this would be great, Thank you!
