Google Search Appliance
From Wikipedia, the free encyclopedia
The Google Search Appliance is a rack-mounted device providing document indexing functionality, that can be integrated into an intranet, document management system or web site using a Google search-like interface for end-user retrieval. The software is produced by Google and the hardware is manufactured by Dell Computers and is based on Dell's PowerEdge R710[1].
The device is supplied in three models: an entry-level appliance capable of indexing up to 300,000 documents (Google Mini), a 2U appliance (GB-7007) capable of indexing up to 10,000,000 documents, and a 7U (2U plus 5U storage) appliance (GB-9009) capable of indexing up to 30,000,000 documents.[2] Later versions of the software allow the connecting of multiple appliances to offer searching "up to a billion" documents[3]. Sales are operated on a licensing scheme which starts as a two-year contract for maintenance, support and software updates.

[edit] Google Mini
The Google Mini is a smaller and lower-cost solution for small and medium-sized businesses to set up a search engine that allows them to index and search up to 300,000 documents.[5]
[edit] Google Search Appliance
The full-fledged Google Search Appliance can be purchased in two separate versions based on the number of documents being indexed. Model GB-7007, a 2U appliance, is used for indexing up to 10,000,000 documents. Indexing up to 30,000,000 documents is done with a GB-9009 7U appliance[2]. Software version 6.0 was released in June, 2009. This software runs on some hardware versions of the GB-1001 model (all units with an "S5" prefix in their "Appliance ID"), and all GB-7007 and GB-9009 models. New features available in this software include:
- Customized and enhanced relevancy tuning to bias certain nodes’ and collections’ results.
- Administration APIs for .net and Java programmers to automate tasks[6].
- Early binding to increase serving performance
- Customization in SAML authentication and Authorization
- Added user results to search results.
- Search-as-you-Type functionality.
- Query translation to 40 different languages.
- Replication of search results
- Clustering multiple GSAs by using a new technology called (GSA)n makes it possible to index upto 1 billion documents[citation needed]
[edit] Older appliances
Google used to sell a 2U appliance (GB-1001) capable of indexing up to 5,000,000 documents, a half-rack cluster (GB-5005) of five 2U nodes capable of indexing up to 10,000,000 documents, and a full-rack cluster (GB-8008) of eight and later twelve nodes capable of indexing up to 30,000,000 documents[2].
