> I guess the reason is that the "lastDoc" is part of the iterator, but the
> "IndexSearcher" is not always the same, so that if there were changes in the
> meantime, the "lastDoc" does not correspond to this "IndexSearcher". This
> might mean the query result is sometimes wrong (matches are not returned, or
> returned twice).
