Hi Guys, My index contains 89k documents and I don't store some of the text fields because they are way too big. When I run a normal search without field collapsing everything works but when I enable field collapsing on the same search, it crashes with a 500 error (exception).
The URL I call is this (for field collapsing): http://mk.example.com:8080/solr/Advisor/select?indent=on&version=2.2&q=*%3A*&fq=&start=0&rows=999&fl=AdvisorID&qt=standard&wt=standard&explainOther=&collapse.field=AdvisorID&collapse.type=normal&collapse.threshold=1 Below is the exception: HTTP ERROR 500 Problem accessing /solr/Advisor/select. Reason: null java.lang.NullPointerException at org.apache.solr.search.fieldcollapse.NonAdjacentDocumentCollapser$FloatValueFieldComparator.compare(NonAdjacentDocumentCollapser.java:451) at org.apache.solr.search.fieldcollapse.NonAdjacentDocumentCollapser$DocumentComparator.compare(NonAdjacentDocumentCollapser.java:263) at org.apache.solr.search.fieldcollapse.NonAdjacentDocumentCollapser$DocumentPriorityQueue.lessThan(NonAdjacentDocumentCollapser.java:197) at org.apache.lucene.util.PriorityQueue.insertWithOverflow(PriorityQueue.java:148) at org.apache.solr.search.fieldcollapse.NonAdjacentDocumentCollapser.doCollapsing(NonAdjacentDocumentCollapser.java:114) at org.apache.solr.search.fieldcollapse.AbstractDocumentCollapser.executeCollapse(AbstractDocumentCollapser.java:259) at org.apache.solr.search.fieldcollapse.AbstractDocumentCollapser.collapse(AbstractDocumentCollapser.java:179) at org.apache.solr.handler.component.CollapseComponent.doProcess(CollapseComponent.java:173) at org.apache.solr.handler.component.CollapseComponent.process(CollapseComponent.java:127) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(SearchHandler.java:195) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:131) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1322) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter.java:337) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:240) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:388) 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:765) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:418) 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$RequestHandler.headerComplete(HttpConnection.java:923) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:547) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:212) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:404) at org.mortbay.jetty.bio.SocketConnector$Connection.run(SocketConnector.java:228) Does anyone know why this is happening? Is there any other patch I can try that will do this same thing without any errors? Thanks in advance, Moazzam
