SEARCH LEAKAGE At other search engines, when you do a search and then click on a link, your search terms are sent to that site you clicked on (in the HTTP referrer header). We call this sharing of personal information “search leakage.” For example, when you search for something private, you are sharing that private search not only with your search engine, but also with all the sites that you clicked on (for that search).
