Rumors about Google buying Twitter were abundant in the last few months but have died down recently after the Mountain View-based company’s officials stated that the two parties could work together without having direct ties. But while buying Twitter outright may be less likely for the time being Google is still very much interested in the service and a recent discovery by the unofficial Google Operating System Blog seems to be confirming a new Google micro-blogging search service.

Most users rely on Twitter's own search engine, which is far from perfect, and in fact searching has become the most important way to use and find new content on the site. There are third-party services, like Tweefind and Twingly, but even those have their drawbacks.

The Google Operating Blog came across a description relating to the new service that read: "Recent updates about QUERY. This is the MicroBlogsearch Universal result group header text. A Microblog is a blog with very short entries. Twitter is the popular service associated with this format."

Google's new search service, judging by its experience and previous products like Blog Search, should be much better and will apparently be incorporated into the standard search based on frequently used keywords or hot topics. Google's micro-blogging search will also sort results by relevancy and, while it will be a 'universal' micro-blogging search, its biggest source is expected to be Twitter.

There is no official word from the Mountain View-based company but it is clearly interested in real-time search and has praised Twitter for its real-time response. "People really want to do stuff real time and I think they [Twitter] have done a great job about it," Google co-founder Larry Page said last month at the Google Zeitgeist conference. "I think we have done a relatively poor job of creating things that work on a per-second basis," he added.
