AnonymousClassScoreDocComparator throws nullreferenceexception --------------------------------------------------------------
Key: LUCENENET-394 URL: https://issues.apache.org/jira/browse/LUCENENET-394 Project: Lucene.Net Issue Type: Bug Environment: Lucene.NET 2.4.0.2 Reporter: Jaap Taal Priority: Blocker I've added a field to my index (Store.NO, Index.UN_TOKENIZED), I've updated a couple of my documents and I'm now sorting on it (after I collected document id's in a HitCollector). My search results in some documents that consist of document with the field and without. I use a simple implementation of SortComparator which implements GetComparable by just returning the passed termtext. I've set a breakpoint at my GetComparable method and I see the correct values (the method is NOT called for documents that don't have the field as a value). When SortComparer.Compare is called, a NullReferenceException occurs in: {code} public virtual int Compare(ScoreDoc i, ScoreDoc j) { return this.cachedValues[i.doc].CompareTo(this.cachedValues[j.doc]); } {code} The expression this.cachedValues[i.doc] is null. Is this a limitation of SortComparer (and its AnonymousClassScoreDocComparator) that all documents in a searchresult need to have a value for the field?? -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
