Description
At index time term vectors are sorted using String.CompareOrdinal. However method IndexOf of class SegmentTermVector invokes System.Array.BinarySearch, which is using String.Compare.
public virtual int IndexOf(System.String termText)
{
if (terms == null)
return - 1;
int res = System.Array.BinarySearch(terms, termText);
return res >= 0 ? res : - 1;
}
The effect is that the IndexOf method always returns a negative number (no match) because the sort order is incompatible with the default comparer.
