Google is set to let users try out an upgraded search technology, code-named Caffeine, that its engineers have been developing for the past several months.

Google Tuesday announced that it is opening the so-called “next-generation architecture” to Web developers and power users to test out. Users can access the as-yet unfinished Caffeine in a Google sandbox, a testing environment that isolates new code from production systems.

The announcement that Google is honing a faster, more accurate and comprehensive search engine comes about two weeks after rivals Microsoft and Yahoo announced that they are partnering up to challenge the search giant. The deal calls for Microsoft’s Bing search engine to power various Yahoo sites, while Yahoo sells premium search advertising services for both companies.
