The file reached the maximum download limit. Check that the full text of the document can be meaningfully crawled.
This is the error you find in the Microsoft Search Server logs when the size of the file being uploaded is greater than 50 MB. This is because the default size is 50 MB for crawling. Hence when the size of the file being uploaded exceeds the allowable limit then the crawler will not be able to crawl the file and throws this error. In this article, we will see how to fix this issue.
The error log screen is shown below:
To allow the files that is larger in size and to be crawled and fully indexed we have to add the MaxDownloadSize dword value to the 50 MB or more.
Go to Run -> Type regedit -> Navigate to the following path and change the value.
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office Server\12.0\Search\Global\Gathering Manager"
Change the following value "MaxDownloadSize"=dword:00000032
Note: Hexadecimal 32 = Decimal 50.
Try restarting the index server and now initiate a full crawl then the files of large size will be shown in the Search Results.
This helped in fixing this issue and the search is showing the results as expected.
