IBM has released a free plug-in that integrates its WebSphere Information Integrator OmniFind Edition enterprise search system with Google's enterprise desktop search tool.

By linking the IBM enterprise search system with Google's PC search tool, users will be able to search for information not only on corporate repositories, such as databases, content management systems, applications and the web, but also on their desktops.

Among the documents the free Google Desktop for Enterprise can index and make searchable on users' PCs are the full text of e-mail, files, viewed web pages and chats.

For example, it can index e-mail from Outlook, Lotus Notes, Netscape Mail and Mozilla's Thunderbird.

The Google product is free, but organisations can choose to buy what Google calls "premium support" for it for a fee of US$20,000 per two years for an unlimited number of users.

Google Desktop for Enterprise is derived from a similar tool for consumers, but the enterprise version has installation, distribution, management and security features for IT departments to use when rolling out and configuring the product for their users.

The IBM WebSphere Information Integrator OmniFind Edition Plug-In for Google Desktop for Enterprise can also be downloaded for free.
