Google Labs is experimenting new search feature.
It is called as Squared.
It will collect the details for the search keyword from many websites and combine them display search results in structured format such as Excel like structure having many rows and many columns.
You can see/test it at http://www.google.com/squared.
Find below the screenshot which show search result for india primeminister.
We can see Name, photo, description, date of birth and some other details of each us president in tabular format.
It will be more useful for doing comparison in Research.

Interestingly, when I did a search for "search engine" the result page didn't show the Google. So I thing it is still in very initial stage of testing.
