“

• Follow the steps below to add new entry in the windows registry:
• Open Registry Editor (RegEdit.Exe)
• Locate the following Key:
  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0\Search\Global\Gathering Manager
• Right Click Gathering Manager > New > DWORD Value. Name it MaxDownloadSize. Double-click, change the value to Decimal, and type the maximum size (in MB) for files that the gatherer downloads.
• RESET the index.
• Start Full Crawl.
