[Perlfect-search] url returned in search result

[webmaster]

I installed Perlfect search a couple of months ago, and I've been 
playing around with it. I've set it up to index via http. When it 
returns search results, however, it doesn't list the urls it used to 
crawl the site; instead, it returns the file name from the server. Example:

instead of http://www.example.com/foo/bar
it returns http://www.example.com/foo/bar.html

Is there something I can change in configuration so that it indexes the 
url instead of the filename?
