Google Inc. (NASDAQ: GOOG) today announced a new edition of the Google Search Appliance™, GSA 6.0, with architecture that indexes all of even the largest organization’s content: limitless linking of appliances to create unparalleled enterprise search power.

The GSA 6.0 allows businesses to:

•    Scale to billions of docs simply - The new GSA can search not just thousands or millions, but billions of documents. With our dynamic scalability feature, you can easily connect multiple GSAs, whether in one location or many, while providing employees an an easy-to-navigate set of results that also unifies information across departments and data stores.

•    Customize across the board - GSA 6.0 comes with options to customize administrative, security and relevancy features. Ranking Framework, Node Biasing and Collection Biasing allow you to fine-tune search results to your needs.  The new Administrative API provides more control for automation of common tasks, and GSA 6.0 now supports both early and late binding, so search results can be screened according to company security policies.

•    Achieve higher quality search results - Along with improved precision in the core algorithms, GSA 6.0 includes social search features, such as Query Suggestions and User-added Results, that aggregate knowledge across the organization for more precise search results . Additionally, cross-language enterprise search also enables enterprise users across the globe to translate their search results in real-time — into whichever language they choose.

•    Deploy the most powerful search architecture - With this release, we are providing new customers with more powerful architecture, regardless of their document count, upgrading the entry-level appliance to the powerful GB 7007 architecture. Today we’re also launching a brand new model for customers with the highest document counts, the GB-9009, with built-in redundancy and enhanced performance, and built on the PowerEdge R710 platform from Dell and powered by Xeon 5500 Series processors from Intel.

“With the GSA 6.0, it’s easy for companies to give all employees the powerful Google search experience inside their business — even if they are searching among billions of documents in dispersed intranets, data stores, languages or geographies,” said Dave Girouard, President of Google Enterprise. “With the improved architecture and software for the search appliance, global businesses can provide secure search across the largest enterprise content repositories — with one GSA system that can scale to billions of documents without limits.”

The GSA handles enterprise search for the smallest and now very largest organizations — like NASA.

“The Google Search Appliance deployment is ramping up across the NASA systems” said David Valliere, Program Manager, eTouch, search integrator for NASA. “The Google Search Appliance 6.0’s new dynamic scalability feature is instrumental to helping search internally, and the customization options mean that search results match employee security authorization levels. NASA has multiple centers and complex intranets, the Google Search Appliance 6.0 can search each autonomously, while still giving unified results that are easy for employees to navigate quickly and help them be more productive — critical when there are rockets to launch and space missions to plan.”

The GSA 6.0 launched at a Google event in Washington DC. Check out what’s new and see the architecture actually needed to search a billion documents at www.google.com/gsa.
