I just tried a search for something where I had a general idea of what would come back and it worked quickly and gave me what I expected. Was this Advanced Search? Did it just time out or give you unexpected (or no) results?
For what it's worth, I saw a couple of minor hiccups on the site this morning. Can you try your search again and see if it works now?
One of the handiest computer tools I've found (I've used this for years) is a (free) program called CCleaner. Under Options/Cookies it will show you all the cookies currently on your computer...and the ability to move the ones that you want to keep into a Cookies-to-Keep column. When you run CCleaner it will remove all the cookies on your computer...less the ones you want to keep.
I run this program every night before I shut down. Clearing cookies is just one of about 25 other things it does that I've ticked.
