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??
