> 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
> Assignee: Scott Lombard
> Priority: Minor
> Labels: exception, fieldcache, sort,
>
> 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??
