no file extension?

[blackbells]

I have not been able to find a good title for my querry as I dont know how to ask the question in words.

Just have a look at what is written in the address bar of google when i search for word "something".

http://www.google.co.in/search?hl=en&q=something&meta=

What I dont understand is the "search?hl=en&q=something&meta=" part.
If there was php or asp/x, it was understandable but there's no file extension here. Can someone please expalin it?

well first it's a query string and second it's using a canonical url. there's some tutorial on the site about it... i think it's call easy urls or something like that. but yea... you'll want to do a search for canonical urls.
