Here is an EXTREMELY cool way to add search capabilities to your blog using the Google API. All you really need to do is sign up for a Google key (for your Google API searches) and use this code to add a nifty little search box to your blog. I've added mine below the calendar in my theme.

BOOYAH! Great find, Tom. I tried this once using the advanced search through the google search site but I didn't have any luck. I've been looking for a reason to futz with the Google API and I need to search my blog so this kills two birds.
