Good point, Grant! To apply the modified stopwords.* and stoplabels.* files to Solr, simply make them available in the classpath. For the example Solr runner scripts that would be something like: java -cp <dir-with-your-modified-stopwords> -Dsolr.solr.home=./clustering/solr -jar start.jar I've documented the whole tuning procedure on the Wiki: http://wiki.apache.org/solr/ClusteringComponent Cheers, S.
