Users who want Google's Realtime Search will have to look elsewhere for the feature because the search engine has apparently disabled it for good. On July 2nd Google's access to Twitter's special firehose expired and it will no longer be available on the search engine.

The Realtime search integrated real-time data from Twitter and other social networking services into the search results in Google. Now the feature's URL leads to nothing but a 404 error page and tweet results no longer appear in search results.

Google released a statement in Search Engine Land about the change:

Since October of 2009, we have had an agreement with Twitter to include their updates in our search results through a special feed, and that agreement expired on July 2.

While we will not have access to this special feed from Twitter, information on Twitter that's publicly available to our crawlers will still be searchable and discoverable on Google.

Google still has the option of reviving the feature in the future but it will not rely heavily on data from Twitter. Google will use real time data from other sources that it will integrate with Google+, the company's new social network. The Realtime search had content from other services like Google news links, Jaiku, freshly updated web pages, Quora, Gowolla and Twitgoo among others. Twitter, however formed the bulk of the Realtime searches.

Twitter is still providing the service with other search engines like Yahoo! and Bing.

Google's decision not to continue with Twitter feed could simply be a matter of the two companies' failure to negotiate price. Users will have to make do with a Realtime search without the comprehensive public tweet or switch to other search engines like Bing or Topsy.
