Xapian discuss - Apr 2007 - Xapian document matching

Hi, i'm wondering is there a possibility to do like  ABCSok do 
(http://nyheter.abcsok.no/), to make "Main article" and "Same
articles"
collapsed to it.
Like on http://news.google.com/?hl=en the same thing. "Parent" and
"same
article on other sites" (they do differ from each other a little bit).
Maybe somebody know how to do that thing or where to read theory on doing such 
things.
Thank you

I find this module on CPAN
http://search.cpan.org/~sid/WordNet-Similarity-1.04/lib/WordNet/Similarity.pm
That's what i mean, to find if there is a similar document in the base and 
collapse follow-ups to a thread.. Is there ary implementation in Xapian?
Thanks
