Has anyone used Katta in production? It looks very interesting and feature-rich, but I'm wondering how stable it is and whether or not it can support fine-grained queries - for example, constant score queries, MultiSearcher, etc.

I think you should take a look at Katta, as this is exactly the type of use case it's designed to handle. http://katta.sourceforge.net/ Other people use the distributed search support inside of Nutch. And Solr has distributed search support, though it's still pretty new. -- Ken -- Ken Krugler +1 530-210-6378 --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
