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.

Forrester Research analyst Matthew Brown says the product improvements may be as dramatic as Google says they are. But taken in context, Google is still trying to play catch-up to a slew of start-ups and giants like Oracle, he says.

"I'm just kind of unimpressed with what they're announcing," says Brown. "They're coming to market so late, with requirements that were established years and years ago."
