Subject Re: Group by in Lucene ?
Date Wed, 05 Dec 2007 12:17:55 GMT

Hey Marcus,

have you already implemented this feature?
I'm searching a group by function for lucene, too.

More precisely I need it in Compass, which is built on top of lucene.

I was thinking about using a HitCollector to get only one result per group.

How did you do it?

Cheers,
Nina
