Configuring iFilter for PDF Search in SharePoint 2010 – Step by Step

What is iFilter by the way?

IFilters are components that allow SharePoint to index content of specific file types, letting users search for content in those files. Using the SharePoint Search we can find documents based on their filename, metadata, or content within a document. By default, the content of Office documents is indexed by the SharePoint crawler, but PDF files are not crawled.

To add support for PDF files you have to add an I-Filter which the SharePoint crawler uses to read through PDF files and add the information to the search index. There are two steps in configuring PDF Search IFilters for SharePoint:

  1. Install the PDF iFilter
  2. Configure the iFilter

Installing IFilter

The Installation of the iFilter 9.0 has to be done on the Index Server(s). How to install ifilter in SharePoint 2010? Download  and install the iFilter installation file for 64-bit machine from http://www.adobe.com/support/downloads/detail.jsp?ftpID=4025

      Well, that’s the GUID for Adobe IFilter as per http://support.microsoft.com/kb/2518465. If you use some other IFilters, like Foxit – This will vary!
