I would definitely take Michael's advice to learn more about the  
overall issue before you get too far.

A quick answer that may help is Windows does not ship with an iFilter  
for PDF built-in. Installing Adobe Reader 8 or higher will install a  
decent PDF iFilter.

I am a little surprised by your question though - I assume that you  
have access to your own source code and could examine the result from  
the iFilter that's being fed to the IndexWriter and compare the  
behavior in the TXT case with the behavior in the PDF case?
