The new 6.0 software also adds more options for IT managers to customize administration, security and search relevancy features.
In addition, GSA 6.0 provides end users with social search capabilities, such as the ability for them to add results.
"Google has matured in its thinking about how enterprises implement search," said Rebecca Wettemann, an analyst with Nucleus Research.
Enhancing the Search Appliance in areas like scale, customization and integration will resonate positively in the enterprise market, where Google's main challenge is being perceived primarily as a consumer-focused company, Wettemann said.
While the Search Appliance's functionality isn't still as sophisticated as that of high-end products from Autonomy and Microsoft's Fast Search, it has moved upstream with this latest round of enhancements, said IDC analyst Susan Feldman.
"The Search Appliance is no longer as much of a black box," Feldman said.
The Search Appliance starts at US$30,000 with two years of technical support for the GB-7007 with a 500,000 document capacity. By purchasing additional capacity on the same box, IT managers can grow a GB-7007's index to 1 million, 3 million, 5 million and 10 million documents.
