Google is experimenting with some different type of searches. What caught my eye was the Timeline and Map Views. It works best for the queries listed on their page http://www.google.com/experimental/, but I tried some of my own & thoroughly loved it!!!
The Timeline Search just add "view:timeline" to your search & it will categorize your results by date. Great if you just want to search a name during a certain period of time.
The Map View I don't see much difference in just plain old Google Maps. If you want to give this a test drive just add "view:map" to your search.
Maybe if enough people give feedback how much they like it they will get it fully functioning sooner.
