To use Windows SharePoint Services' site search, you must choose the Server Farm setup option during Windows SharePoint Services installation so that you can later specify the path to the Microsoft SQL Server instance that will host Windows SharePoint Services. To configure Windows SharePoint Services to use the SQL Server Full-Text Search component, navigate to the Windows SharePoint Services Central Administration—Configure Full-Text Search page and select the Enable full-text search and index component check box. Site search is available only through SQL Server, not through Microsoft SQL Server Desktop Engine (MSDE).
