Example:

http://www.google.ae/search?q=searchstring

&ct=ibn11-hp

&oi=ddle

&biw=320

&bih=74

&emsg=NCSR

&noj=1

&ei=string of 20 chars

What these mean? 'Biw' is probably width and 'bih' is height, in turn, but the other ones?

I believe that 'oi' is the type of logo etc. when ddle is reserved for Doodles. And 'ct' includes some chars of Doodle's name, a year when published (2011) and the location; hp is home page?

noj means no javascript

Thanks. OK, the example is made with Opera Mini...
