Search Community Toolkit
The Search Community Toolkit is comprised of a number of tools and code samples that have been contributed to enhance the Microsoft search experience (Microsoft Office SharePoint Server 2007 (MOSS) Search, Search Server 2008 and Search Server 2008 Express).

The tools are available on codeplex here: Search Community Toolkit
