Google Desktop Search improves upon the beta version with the ability to search over the full text of PDF files and the meta-information stored with music, image and video files.

In addition, the software supports Firefox and Netscape browsers, as well as Thunderbird and Netscape e-mail clients. The search tool is also available in Chinese and Korean languages.

With this release, Google jumps ahead of rivals Microsoft Corp. and Yahoo Inc., which have similar free products still in beta.
