As per Microsoft: "This event record indicates that the file listed did not get indexed because it generated too much data relative to the physical size of the file. The file will appear in the unfiltered list. This might be normal, or it might be caused by a problem in the filter being used". See MSW2KDB
for additional information about this event.
If the problem is not in the filter being used, then you have to change the MaxFilesizeMultiplier registry setting located in:
MaxFilesizeMultiplier represents maximum amount of data (output) which can be generated from a single file, based on its size. This value is a multiplier. A value of 4 means that a file can generate up to 4 times its size in content index data. See Index Server Registry Parameters link below.
The file <full file path> did not get indexed because it generated too much data relative to the physical size of the file. The file will appear in the unfiltered list. This may be normal, or it may be caused by a problem in the filter being used. If you verify that the problem is not caused by the filter, you can increase the amount of data Indexing Service allows per document. To do that, see the The Microsoft Platform Software Development Kit for information about setting the MaxFilesizeMultiplier registry setting. See Indexing Service event messages link.
