Pdf document title in nutch search

[Håvard W. Kongsgård]

When searching with nutch the title of pdf documents is a url to the 
file like:
http://www.ists.dartmouth.edu/library/wse0901.pdf
I have noticed that google and ultraseek creates a normal title like:
WebALPS: A Survey of E-Commerce Privacy and Security Applications

Is it possible to make nutch do the same?
