iFilters for SharePoint Search

1 minute read

Once you have your SharePoint server up and running and begin to build up a corpus of content, you may find that certain documents aren’t turning up in searches.  This may be due to not having the appropriate iFilters installed.  From the Wikipedia entry:

IFilters are plugins that allow the Windows Indexing Service and the newer Windows Desktop Search to index different various file formats so that they become searchable. Without an appropriate IFilter, contents of a file cannot be indexed.

Here are a few important ones.  If your organization uses a particular type of file frequently, make sure to look into the iFilter for it.  The Wikipedia article above has links to many free and for-pay iFilters.  Note that there may be different versions of iFilters for 32-bit vs. 64-bit operating systems, different file versions, etc., so be sure to get the right ones for your needs.
