Content within a PDF Document is not crawled in SharePoint 2010
You will see n o search results are returned while trying to search for keywords within PDF Documents on the SharePoint site. The reason why it cannot crawl those is because of Insufficient permissions for the 'Default Content Access Account' on the PDF iFilter folder. Below are the steps to resolve this issue: ========================================= • Go to following location on your SharePoint Index and Crawl Server "%Program Files%\Adobe\Adobe PDF iFilter 9 for 64-bit platforms\bin" directory or the installation location of the pdf ifilter. • Add the 'Default Content Access Account' of the Search Service Application. Make sure you at least provide 'Read', 'Read & Execute' and 'List Folder Contents' permissions to the account. • Once you provide above said permissions then go ahead and start a Full Crawl. • In certain cases, you may also have to reboot the SharePoint servers.
