Hi Vadim, I've had limited connectivity, so I couldn't check out the complete 1.4.1 code and test the changes. Here's what you can try:
In this file: http://svn.apache.org/viewvc/lucene/solr/tags/release-1.4.1/contrib/clustering/src/main/java/org/apache/solr/handler/clustering/carrot2/CarrotClusteringEngine.java?revision=957515&view=markup around line 216 you will see: for (Document doc : docs) { docList.add(doc.getField("solrId")); } You need to change this to: for (Document doc : docs) { docList.add(doc.getField("solrId").toString()); } Let me know if this did the trick. Cheers, S.
