Google Real Time Search

This month Google announced a new search tool: real-time search.  Google's real-time search component is different than its traditional search tool.  While its traditional search tool crawls websites periodically and stores them in its index, Google's real-time search tool incorporates website posts in real-time, as they are posted. 

This feature is automatically included through its normal search page, so you don't need to do anything special.  If you happen to search for a keyword this is popular right now, the real-time results will show up in the normal search results page as shown below.

Under the "Latest results for" section, you'll notice a scroll box wich contains real-time results from accross the web.  As the posts flow in, the scroll window rolls the posts down every few seconds. 

If you want to check it out, a great place to start is on Google Trends page, which always shows the hot topics.
