The printing press changed the communication from one-to-one to one-to-many. The web brings it to many-to-many. Google has real-time search . We can make a strong point stating that Google has 11 years of experience with ranking based on relevance, not just based on sort-by-date.
To get to real-time search, you’ll click the “Show options” link above the search results. Then you’ll see a “Latest” option. Looks like there’s also an “Updates” link to restrict it to updates from sites like Twitter, FriendFeed, etc. Example of see that a vaccine was out from a tweet a few seconds ago.
Realt-time search works on mobile (iPhone, Android) too. Google will add really-hot topics to the Hot Trends page to see these real-time updates.
Google is processing “over a billion documents a day” from the real-time web to work! That is amazing, compared to even the largest competitive numbers.
The main four pillars of search are: comprehensiveness, relevance, user experience, and speed/freshness. Google Real Time search gives you that in a blinking eye.
“Light can travel around the world in 1/10th of a second, and we won’t rest until the speed of light is the only barrier to getting good search results to you.”
