question is, is there any way to upload a file using File Attach, and have Z-catalog automatically index it? What is "File Attach"?

If you upload your file in your own method, then you can call "catalog_object" in that method to catalog the file. I fear that with the normal catalog configuration, this will only catalog the files meta data not its content. This is reasonably as many files will be binary and indexing binary content is not a good idea. If you need to index the content, then you should probably derive a new class "TextFile" which has a method "PrincipiaSearchSource" (do not ask why we have this strange name...). Let this method return whatever you want to have indexed from your file. Dieter
