CENTRAL ADMINISTRATION
Now in SharePoint itself, you need to configure the search service to index files with the .pdf extension:

1. Go to CA and open up the Shared Service under Shared Services Administration.
2. Click Search Administration under the Search section.
3. Click File Types in the left nav bar and then click New File Type.
4. Enter “pdf” and click OK.

ICONS
You will also want to display the PDF icon next to PDF Documents in SharePoint.  You can download the icon from here:

http://www.adobe.com/images/pdficon_small.gif

and copy it into the 12 hive folder here:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\TEMPLATE\IMAGES

Then open up this XML template file:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions \12 \TEMPLATE\XML\DOCICON.XML

and add the this line in the <DocIcons.ByExtension> section if it isn’t there already:

<Mapping Key=”pdf” Value=”pdficon_small.gif”/>

REGISTRY
Now on to the registry changes you need to make on each index server.  Make sure to backup your registry before making any changes.  These two changes will register the Adobe PDF iFilter with the Office Search service.  The values that need to be changed are:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0\Search\Setup\ContentIndexCommon\Filters\Extension\.pdf

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\Search\Setup\ContentIndexCommon\Filters\Extension\.pdf

Both values should be changed to:

{E8978DA6-047F-4E3D-9C78-CDBE46041603}

SYSTEM PATH
Now you need to add the Adobe install directory to the System Path envrionmental veriable so that the search service can find the dll which provides the iFilter service:

1. Right click My Computer
2. Click Properties
3. Click Advanced
4. Click Environment Variables
5. In the bottom half of the window, find the Path variable and double click it.
6. At the end of the value, add:

;C:\Program Files\Adobe\Reader 9.0\Reader

RESTART SEARCH SERVICES
Now you need to restart the Office Search service so that all changes are reflected. Open up cmd prompt and type

sc stop osearch [press enter]
sc start osearch [press enter]

Or just restart it via the Services MMC.

If you already have PDF documents in SharePoint that you want to search inside, you have to ”Reset all crawled content” in Search Settings and then begin a new ”Full Crawl” under Content Sources.
