Hi, I've been researching about clustering with Lucene. Here is what I've found so far,
1) Lucene clustering with Carrot2 - http://download.carrot2.org/head/manual/#section.getting-started.lucene - but, this seems suitable for only smaller size index (few hundred documents) - http://download.carrot2.org/head/manual/#section.advanced-topics.fine-tuning.choosing-algorithm 2) Lucene clustering with Mahout - http://www.lucidimagination.com/blog/2010/03/16/integrating-apache-mahout-with-apache-lucene-and-solr-part-i-of-3 - I'm not very sure if this is ready for prime time yet, there seems to be very few examples on how to do this. Has anyone tried this with large index size (millions of documents)? 3) Some clustering library in Lucene's contribution folder - https://issues.apache.org/jira/browse/LUCENE-1421 - this doesn't seem to be officially supported and last update to it was an year back. Has anyone tried this? 4) Lucene clustering with Terracotta - http://orionl.blogspot.com/2006/11/clustering-lucene.html - I'm not sure how to do this, there doesn't seem to be much activity around this. We got large indexes - over 500 million records, we usually partition our index after 20 million records. There are total of 20 fields in our index, of which we are trying to cluster 5 fields. Is there any clustering solution for Lucene that would work for us? Carrot2 looked the most active and promising, but it's clearly recommended for a small index size. Any other suggestions?
