All very true, but if you're serious about looking at every item that results from some search (because you're researching, not merely browsing), then you will use the advanced search interface to get a CSV file (or JSON, XML, HTML, or RSS, according to preference) which you can then work with entirely locally. You'll be able then to keep track of everything you do with every item in that list.
