[ic] Searching for a UA string

[Grant]

I'm having trouble searching for UA strings with the IC search
function.  I'm stacking the search parameters like this:

sf=user_agent
se=Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)
op=ne
nu=0

and I've also tried these:

se=Mozilla\/5.0 (compatible; Googlebot\/2.1; +http:\/\/www.google.com\/bot.html)

se='Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)'

Is there an obvious problem with this?
