Changing the Maxmium File Size in your Enterprise Search Index

Posted Friday, February 8, 2008 2:00 PM by CoreyRoth

In MOSS Enterprise Search, the maxium size of a file that it will index is 16 MB.  This is probably not an issue for most people, but some organizations do have large PDFs, PowerPoints, etc.  This is becoming a little more common knowledge, but I thought I would post it to make more people aware of it.  To change it, you need to add a DWORD at the following registry key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0\Search\Global\Gathering Manager

Add a new DWORD value of type Decimal called MaxDownloadSize.  The value should be in megabytes so a value of 50 would represent 50MB.  After you change this, you'll need to restart the Office SharePoint Server Search service and perform a full crawl.  Again, this is becoming more common knowledge, but I thought it was still worth mentioning.
