I wonder whether Google has any edge cases like this one John Forsyth found in Bing?

At first I thought it was a problem with the URL I was searching for, but it turns out any search containing the words "view topic" will crash Bing.

See for yourself, with one of the examples he posted (Follow the link above for more):

"what topics do they discuss on The View?"

It turns out that Bing is filtering out searches for phpBB that involve viewtopic.php (a huge security problem, seemingly) - and a bunch of other searches are merely collateral damage. Go read the whole story - it's fascinating stuff.
