Google has extended the languages supported by Google Desktop for the Mac.

The software now supports nine additional languages, including Chinese Simplified and Traditional, Dutch, UK English, French, German, Italian, Japanese, and Spanish. It already supports US English.

Like Apple's Spotlight, Google Desktop is Google's search machine that can explore all the data and content held on a user's local machine, it will also explore the web. Search results are delivered in a webpage similar to that users find when engaged in an online Google search.

Additional improvements in the new release include giving the software the intelligence to discount spam mails from search results and the introduction of support for contact groups in Address Book and Entourage.

The software is available here for download.
