TechCrunch reports that Google will soon announce a cross language search engine. Search queries will be auto translated into other languages and all results will be translated on the fly, back to the original query language.
Considering that Google launched Blogger in Hindi and more recently, Google News in Hindi, Google has the ability to do effective transliteration into Hindi — and so it shouldnt be very difficult for them to enable search in Hindi and display search results in Hindi.
Yahoo, Rediff, Guruji — watch out !!
