Seemed like a good idea at the time
ScriptyGoddess posted a link to tip from NSLog(); suggesting a cool way of automatically searching from 404 pages, which I implemented a couple of days ago.
Unfortunately I didn't take Googlebot into account, and when it visited today it generated rather alot of 404 errors in rather a short space of time. The server didn't like that (all of a sudden alot of cgi scripts running doing alot of big database queries).
So the automatic search feature disappeared quite quickly. :-)
