Out of box SharePoint search does not includes the PDF file support which means it didn’t recognize that you have uploaded a file with extension .pdf. There is very easy integration of Adobe Ifilter with SharePoint just by doing some administrative changes on SharePoint server. I am documenting the steps below:
1) Install PDF iFilter 9.0 (64 bit) from PDFiFilter64installer.zip.
2) Download PDF icon picture pdf16.gif from Adobe web site and copy to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\IMAGES\
3) Navigate to Central Admin | Manage service applications | Search Service Application and once there click on “file types” to add the PDF file type.
4) Add the following entry in docIcon.xml file, which can be found at: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\XML
<Mapping Key=”pdf” Value=”pdf16.gif” />
5) Open regedit.
6)Navigate to the following location:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\14.0\Search\Setup\ContentIndexCommon\Filters\Extension
- Right-click > Click New > Key to create a new key for .pdf
- Add the following GUID in the default value
7) Restart the SharePoint Server Search 14
8) Reboot the SharePoint servers in Farm
9) Upload any sample PDF document(s) to the document library of your site.
10) Perform FULL Crawl to get search result or Perform incremental to include PDF files.
11) Once the crawl is completed we will get search results.
Now your SharePoint will support PDF files in search content. Happy sharepointing :)..
