The easiest way to fix this is to update the stop words list used by Carrot2, see http://wiki.apache.org/solr/ClusteringComponent, "Tuning Carrot2 clustering" section at the bottom. If you want to get readable cluster labels, it's best to feed the raw text for clustering (cluster labels are phrases taken from the input text, if you remove stopwords and stem everything, the phrases will become unreadable).
