MOSS 2007: Creating a custom AJAX UserControl that will query the SharePoint Search Query Object Model to perform searches

This article provides a step-by-step guide on building a custom AJAX UserControl in MOSS 2007 that uses the SharePoint Search Query Object Model to perform searches. It covers copying necessary assemblies (Microsoft.Office.Server.dll and Microsoft.Office.Server.Search.dll) to the web application's bin folder, creating the UserControl with inline server code, and implementing an UpdatePanel for asynchronous search results. The tutorial includes code for a search button click event that queries the search service using a keyword and displays results without page reloads, leveraging AJAX for a smoother user experience. It is a technical guide for developers working with SharePoint 2007 and ASP.NET AJAX.
