The Foxit PDF IFilter is "designed to help users to index a large amount of PDF documents & then quickly find text within these documents." Whether files, email attachments or database records, Foxit PDF IFilter helps you find the text you are looking for. The tools supports the following Microsoft products: Windows Indexing Service, MSN Desktop Search, Internet Information Server, SharePoint Portal Server, Windows SharePoint Services (WSS), Site Server, Exchange Server, SQL Server and all other products based on Microsoft Search technology. If you download this to use with Vista's built-in search, you will need to rebuild the search index. To do this, open the Indexing Options dialog box from Control Panel, click the Advanced button, and then click "Rebuild." Thanks to Ed Bott's blog for this great tip!
