This check determines whether you have installed a third party iFilter for PDF files.
Explanation
In a typical company that uses SharePoint the most common documents typically stored in SharePoint are Microsoft Office files like DOCX, XLSX, PPTX, and PDF files. SharePoint is a great tool that indexes all these files and serves them as search results. Microsoft Office files are supported out-of-the-box, but additional steps are required to configure the search contents of PDF files (support for PDF search was added to SharePoint 2013).
Solution
To fix issues with SharePoint 2010 not searching the contents of PDF files, you need to do the following:
Configure SharePoint Foundation search service via Central Admin (or PowerShell)
Download the Adobe PDF icon (select Small 17 x 17) and save it to a folder on your SharePoint server as pdficon_small.gif
Download the script below and place it to the same folder as Adobe PDF Icon
Run the script as administrator from the Powershell shell
clsfunctionGet-FileFormatDate {param( [DateTime]$date = [DateTime]::now )return $Date.ToUniversalTime().toString( "yyyy-MM-dd_hh-mm-ss" )}if((Get-PSSnapin | Where {$_.Name -eq "Microsoft.SharePoint.PowerShell"}) -eq $null) {Add-PSSnapin Microsoft.SharePoint.PowerShell;}$continue =Read-Host"This script will change SharePoint configuration files, registry and will restart your IIS!

The same process applies to SharePoint 2007. However, since there was no PowerShell at the time, we recommend using the following cookbook to perform the task.
