After doing some searching last night, clicking through to a result and doing some reading, then returning to the original SERP, I noticed a notice "You recently searched for facts" below one fo the results that I had not yet visited.
Yes, I am seeing this for quite a few days. From an ip Google keeps track of all the pages you have visited and even the searches through its SERP and it displays below. After an hour it will show "You have searched for facts about an hour ago" . But one more thing is that I really do not see the same things each time even though I perform same searches.
