Google at Searchology announced many new features that will enrich user experience making search much better and more user friendly, changing the overall meaning of search

Udi Manber, Vice President Engineering, Google highlighted few features like User location based search results, Real time search results for queries like flight numbers, ’Slice and Dice’ feature using which search result can be bifurcated on the basis of time letting the users get only the relevant search results like latest news in Washington DC.
Users can also categorize results on the basis of news, videos, images , blogs, results etc . They also revealed their strategy towards Mobile search and expect it to grow much faster than desktop search.

Google is putting every step forward to make the search more user friendly and enrich the search capability so that users don’t have to go to irrelevant sites and can browse the relevant content before even clicking the mouse.
For eg: A search for a Flight number in google will provide the time of the flight, whether it is delayed or in time etc eliminating the need to go to a particular site and check the flight status saving lot of time and effort for the users.
It also introduced a ‘Slicing and Dicing’ feature via Google Search Options using which users can customise their search based on media like news, videos, blogs, images etc coupled with the ‘recency’ fetching only the recent results users are interested in . For example people can only be interested only in which new devices Android is ported on, Not in What Android is?
Google Squared is a new concept for the facts , that will fetch and organise facts in the form of a table . For example a search for a processor will make a table of the list of processors available on the basis of speed , make etc eliminating all the work of the user writing a review about processors. Here is a nice demo featuring the use of Google Squared, this feature will be introduced by next month.

Google will also enrich it snippets to provide more information in a small text block under each search results providing quick answers to user queries. Google is offering tools to website owners to help providing more information for the snippets.
Google seems to be really pushing for a more meaningful and relevant search and it seems that such advancements from google doesn’t give any room for any so called Google Killer search engines.

are they doing through the use of metadata ? Some body has to post the information meaningful way in order to be able to be displayed by search engine
They will soon publish the tools for webmasters as per the presentation and webmaster can use.
