Xapian discuss - Jan 2007 - xapian query group result by domain?

Hi

I know it might not possible, but just want to try my luck.

say, for a web search engine backed by xapian....
Is it possible to group the result by domain just like google's [ More 
results from www.abc.com ],
when there are more than 1 results from the same domain?

Or, anyone have some work around to do it?

Cheers

Put the domain name in a value and use
Xapian::Enquire::set_collapse_key() to collapse matches with the same
domain:

You can then use Xapian::MSetIterator::get_collapse_count() to decide
when to add the "More results from X" link:
