The search is the most important thing on web now a days as people don’t want to remember the URL but prefer to search.
People want to type less or in other words they want to reach the most relevant results as fast as possible.
And that's why Google has been trying to improve on the ways to search. Google has moved one step ahead and provided more ergonomic and technically complex ways to search.
Some of the ways which have been introduced by Google are:
On main Page you can search by voice. Just click on Mic icon on search box and say which you want to search and you will get results.
On image search page click on camera icon on the search box and it will let you enter the image URL or to upload the image file which you need to search and then on search it will give results.
These ways can help you more on the move and can let you do more with information.
