Other new features include a personalized search experience that allows administrators to adjust search results for different user groups, based on department or function; e-mail alerts for topics and documents of interest that employees can subscribe to; and a spellchecker for French, Italian, German, Spanish, Portuguese and Dutch.

"Taking Google's core search technology and optimizing it for business use, the Google Search Appliance provides universal search across a variety of internal and external sources—including file shares, intranets, databases, applications, hosted services and content management systems," according to a release on Google's Web site.

Other new security and control features include native support for Kerberos, which enables silent authentication; metadata biasing; and advanced reporting features such as exportable daily and hourly result sets, top queries, special feature usage, and more.

The Search Appliance, still available in its familiar bright yellow, also now offers localized administration in 27 different languages, according to Google.

Solution providers can purchase the Search Appliance through Ingram Micro. The appliance contains Google software running a Dell server platform.

Google now has 20,000 enterprise search customers, including more than 10,000 Search Appliance customers, according to TechCrunch.org. The remainder use the company's hosted search and other enterprise products.
