This issue can occur if some text files are too large for the server to index by using the default SharePoint Portal Server settings, which are configured for performance reasons.
Indexing Large Text Files
If you are indexing large text files (.txt), to resolve this issue, change the MaxTextFilterBytes registry value.
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
Double-click the MaxTextFilterBytes value, change the value to Decimal, and then type the new value. The value is the maximum size (in bytes) for files that the text filter indexes. (The default value is 25,000,000 bytes, or approximately 25 megabytes.)
See the "More Information" section of this article for a description of the MaxTextFilterBytes value.
