Hi, the quick and dirty way sound good:) It would be great if you can send me a patch for 1.4.1.
By the way, i tested Solr. 3.5 with my 1.4.1 test index. I can search and optimize, but clustering doesn't work (java.lang.Integer cannot be cast to java.lang.String) My uniqieKey for my docs it the "id"(sint). These here was the error message: Problem accessing /solr/select/. Reason: Carrot2 clustering failed org.apache.solr.common.SolrException: Carrot2 clustering failed at org.apache.solr.handler.clustering.carrot2.CarrotClusteringEngine.cluster(CarrotClusteringEngine.java:217) at org.apache.solr.handler.clustering.ClusteringComponent.process(ClusteringComponent.java:91) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:194) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:129) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1372) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:356) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:252) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1212) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:399) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:182) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:766) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:450) at org.mortbay.jetty.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:230) at org.mortbay.jetty.handler.HandlerCollection.handle(HandlerCollection.java:114) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:326) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:542) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:928) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:549) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:212) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.jetty.bio.SocketConnector$Connection.run(SocketConnector.java:228) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:582) Caused by: java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String at org.apache.solr.handler.clustering.carrot2.CarrotClusteringEngine.getDocuments(CarrotClusteringEngine.java:364) at org.apache.solr.handler.clustering.carrot2.CarrotClusteringEngine.cluster(CarrotClusteringEngine.java:201) ... 23 more It this case it's better for me to upgrade/patch the 1.4.1 version.
