Rails: get params from a string

Say I have a string that is a url with params in it:

http://www.google.com/search?hl=en&client=firefox-a&hs=zlX&rls=org.mozilla%3Aen-US%3Aofficial&q=something&cts=1279154269301&aq=f&aqi=&aql=&oq=&gs_rfai=

How can can I form an array of all the params from the string? I'm aware of the params array that you can access but I'm talking about just any arbitrary string, not one part of the request.

Not sure if there is a rails shortcut, but:

url = 'http://www.google.com/search?hl=en&client=firefox-a&hs=zlX&rls=org.mozilla%3Aen-US%3Aofficial&q=something&cts=1279154269301&aq=f&aqi=&aql=&oq=&gs_rfai='

params = CGI.parse(URI.parse(url).query)

#=> {"hs"=>["zlX"], "oq"=>[""], "cts"=>["1279154269301"], "aqi"=>[""], "rls"=>["org.mozilla:en-US:official"], "hl"=>["en"], "aq"=>["f"], "gs_rfai"=>[""], "aql"=>[""], "q"=>["something"], "client"=>["firefox-a"]}

params = CGI.parse(url)

is almost there gives you: 

#=> {"hs"=>["zlX"], "oq"=>[""], "cts"=>["1279154269301"], "aqi"=>[""], "rls"=>["org.mozilla:en-US:official"], "aq"=>["f"], "http://www.google.com/search?hl"=>["en"], "gs_rfai"=>[""], "aql"=>[""], "q"=>["something"], "client"=>["firefox-a"]}
