Microsoft has just released the Office 2010 Filter Packs. The Microsoft Filter Pack is a single point-of-distribution for Office IFilters. IFilters are components that allow search services to index content of specific file types, letting you search for content in those files. They are intended for use with Microsoft Search Services (Sharepoint, SQL, Exchange, Windows Search).
The Filter Pack includes:
Legacy Office Filter (97-2003; .doc, .ppt, .xls)
Metro Office Filter (2007; .docx, .pptx, .xlsx)
Open Document Format Filter
The 2007 Office System Convertor – Microsoft Filter Pack is a pre-requisite for installing Exchange 2010. This filter pack is used to index the contents of Office 2007 file formats. With the release of Office 2010, Microsoft has now updated the filter pack.
