Microsoft Search Server
Enterprise search software from Microsoft / From Wikipedia, the free encyclopedia
Microsoft Search Server (MSS) was an enterprise search platform from Microsoft, based on the search capabilities of Microsoft Office SharePoint Server.[1] MSS shared its architectural underpinnings with the Windows Search platform for both the querying engine and the indexer. Microsoft Search Server was once known as SharePoint Server for Search.[2]
Microsoft Search Server was made available as Search Server 2008, which was released in the first half of 2008. In 2010, Search Server 2010 http://www.microsoft.com/enterprisesearch/searchserverexpress/en/us/technical-resources.aspx became available, including a free version, named Search Server 2010 Express. The express edition featured the same feature-set as the commercial edition, including no limitation on the number of files indexed; however, it was limited to a stand-alone installation and could not be scaled out to a cluster.[3] A release candidate of Search Server Express 2008 was made available on November 7, 2007 and was scheduled to Release to Manufacturing (RTM) in sync with Search Server 2008.
