I recently came across an issue with a customer that uses large files in WSS, notably, .CAD files; as a result these files were either - one, not indexed or two, indexing did not gather the required information from the file to provide useful search criteria.  To remidy the issue MaxDownloadSize was increased to 64MB while leaving the MaxGrowFactor at 4, this will essentially permit the index filter to produce up to 256MB (64 x 4) of text from a given file, the default setting in SPS is 16MB MaxDownloadSize and 4 MaxGrowFactor, limiting the index filter to 64MB max.

To set the MaxDownloadSize on an Index/Job server:

1. On the taskbar, click Start, and then click Run.
2. Type regedit, and then click OK.
3. In Registry Editor, navigate to HKEY_LOCAL_MACHINESoftwareMicrosoftSPSSearchGathering Manager.
4. In the details pane, right-click MaxDownloadSize, and then click Modify.
5. In the Edit DWORD Value dialog box, in the Value data box, type the number for the maximum size of file that can be crawled. Ensure that Base is specified as Decimal.
6. Click OK. Close Registry Editor.
7. Perform an Incremental (inclusive) crawl.

To set the MaxGrowFactor on an Index/Job server:

1. On the taskbar, click Start, and then click Run.
2. Type regedit, and then click OK.
3. In Registry Editor, navigate to HKEY_LOCAL_MACHINESoftwareMicrosoftSPSSearchGathering Manager.
4. In the details pane, right-click MaxGrowFactor, and then click Modify.
5. In the Edit DWORD Value dialog box, in the Value data box, type the number for the grow factor which is multiplied by the MaxDownloadSize to determine the maximum size of a file that can be indexed. Ensure that Base is specified as Decimal.
6. Click OK. Close Registry Editor.
7. Perform an Incremental (inclusive) crawl.
