A rack-mounted computer from Google that was used to index documents for a company. Introduced in 2002, the device was dropped in 2018 in favor of its cloud-based replacement.
Using Google's proprietary Google File System (GFS), appliances were available that indexed from a half million to millions of documents. The devices supported searching across servers, intranets, databases, hosted services and content management systems. It functioned like a Web search engine; crawling the content in the enterprise and producing master indexes of all the data. See
