… is a bookmarklet that removes everything but the actual search query from Google search URLs. That is, all query string parameters except for the q (query) parameter are stripped from the URL. The page is then reloaded with the stripped URL.
http://www.google.com/search?client=safari&rls=de-de&q=test&ie=UTF-8&oe=UTF-8

becomes
http://www.google.com/search?q=test

A typical Google URL (i. e. searching for test) for me looks like this:
http://www.google.com/search?client=safari&rls=de-de&q=test&ie=UTF-8&oe=UTF-8
This URL contains much more information than the thing you were actually googling for ("test"). For example, it encodes:
de-de, which means Germany)But this is just a simple example; there can be a lot more such information in other cases.
Drag the following Bookmarklet to your browser's bookmark bar:
Then, whenever you want to minimize a Google search URL, click on the Bookmarklet, and voilà, there's your Google search page with minimized URL, ready to be copied and used elsewhere.
