Woops. Thanks Rick, that was it. I'm so used to typing "str" that it became white noise. On 29 August 2017 at 16:03, Rick Leirwrote: > Craig, > Just a guess, but your threshold is in a string field.

Craig, Just a guess, but your threshold is in a string field.

ClassCastException when using HighFrequencyDictionaryFactory with SearchComponent
Hi, I've been trying to get a suggester working with the HighFrequencyDictionaryFactory but when setting the threshold I'm getting a ClassCastException when the dictionary is built. Could someone please advise? To reproduce: 1. Download solr 6.6 2. Replace the SuggestComponent within the techproducts' solrconfig.xml with: mySuggester FuzzyLookupFactory HighFrequencyDictionaryFactory 0.005 cat string false 3. Run the techproducts example: "solr start -e techproducts" 4. Visit http://localhost:8983/solr/techproducts/suggest?suggest=true=true=mySuggester=elec I then see the following response: 500 5 java.lang.String cannot be cast to java.lang.Float java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Float at org.apache.solr.spelling.suggest.HighFrequencyDictionaryFactory.create(HighFrequencyDictionaryFactory.java:47) at org.apache.solr.spelling.suggest.SolrSuggester.build(SolrSuggester.java:179) at org.apache.solr.handler.component.SuggestComponent.prepare(SuggestComponent.java:179) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:270) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:173) at org.apache.solr.core.SolrCore.execute(SolrCore.java:2477) at org.apache.solr.servlet.HttpSolrCall.execute(HttpSolrCall.java:723) at org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:529) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:361) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:305) at org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1691) at org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:582) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143) at org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:548) at org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:226) at org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1180) at org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:512) at org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185) at org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1112) at org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141) at org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:213) at org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:119) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:134) at org.eclipse.jetty.rewrite.handler.RewriteHandler.handle(RewriteHandler.java:335) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:134) at org.eclipse.jetty.server.Server.handle(Server.java:534) at org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:320) at org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:251) at org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:273) at org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:95) at org.eclipse.jetty.io.SelectChannelEndPoint$2.run(SelectChannelEndPoint.java:93) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.executeProduceConsume(ExecuteProduceConsume.java:303) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.produceConsume(ExecuteProduceConsume.java:148) at org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.run(ExecuteProduceConsume.java:136) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:671) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:589) at java.lang.Thread.run(Thread.java:745) 500 Thanks, Craig
