After introducing the final version of its Desktop Search application in March, Google has now launched a corporate version of the same program for deployment in corporations where important data is stored usually on private servers.

The enterprise version of Desktop Search looks and operates similar to its regular, end-user application, but it further adds features that may come in handy in enterprise situations. These features include, but not limited to, central control of user features and preferences, the ability to encrypt user data, searching index files and easy deployment on local Intranet within the company’s infrastructure.

Google’s Desktop Search indexes numerous file formats including Word, Excel, PowerPoint, PDF, MP3, image, audio and video files. In addition to the aforementioned file extensions, it also enables users to search their e-mail messages. The supported e-mail clients include Outlook, Outlook Express, Netscape Mail, Mozilla Mail, Thunderbird and Lotus Notes.

The enterprise version even indexes AOL instant messenger’s instant messages, but it doesn’t currently support Yahoo or MSN messenger.

Google said by combining the enterprise edition of its Desktop Search application with Google Search Appliance and Google Mini, companies can search almost anything on their local Intranets instantly.

In order to assist companies with the deployment, Google is offering a premium support package that costs $10,000 per year for 1,000 users. The price goes up by $10,000 a year per 1,000 users.

Google also said that companies that don’t seek technical support can download the Enterprise Desktop Search for free.
