Scott Lombard resolved LUCENENET-394.

    Resolution: Won't Fix
      Assignee: Scott Lombard

I changed the priority on this item to minor.  I am going to wait a few days before closing
it to get a feel for what the community wants to do about bugs pre 2.9.2.

> 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??
