There is an article in BBC http://news.bbc.co.uk/2/hi/programmes/click_online/6972079.stm about how search engines record details of users' search patterns.
I am curious to know, how do search engines get user details when a person uses the search facility. Normally only the IP address of the computer is available and that too changes dynamically. So except for city location of the computer, how do they know the user details?
Log into gmail and then open google search in a new tab. You'll notice that the search page shows you as logged-in in the top right corner. That could be one way to track usage.
Imagine; people logging in and then searching.
