favorite search interfaces on the Web

[Lou Rosenfeld]

I'm looking for Web4Lib'ers' favorite examples of really good search
interfaces for Web sites, ones that go beyond the simple
"just-type-your-question-in-the-box-and-the-devil-knows-what-will-come-of-it" 
variety.  These shouldn't be ones that are for the Web in general (e.g.,
Alta Vista), but for specific, individual Web sites. 

Thanks for your help!
