By sheer accident I stumbled across the google search results display that matches results to a timeline, here is a technology timeline
This apparently lists results that have both your search keyword and a date. I cannot figure out how I got there, but if you take any standard results, say the big wide search on technology. From the results, on the left side bar, click the link for timeline.
Now you can adjust the time range, or change the search terms, this time, say I wanted to create a search history timeline for China
It could be an interesting activity/exercise to create other timelines.
Google embeds surprising functional bits i search results. Looking to calculate a currency exchange? Just google “currency exchange” and you get a widget calculator right there.
Have you found other embedded tools in search results?
Thanks for the surprise serendipity (as if there were any other kind!)
