instead.
public interface SortComparatorSource
Expert: returns a comparator for sorting ScoreDocs.
Created: Apr 21, 2004 3:49:28 PM This class will be used as part of a key to a FieldCache value. You must implement hashCode and equals to avoid an explosion in RAM usage if you use instances that are not the same instance. If you are searching using the Remote contrib, the same instance of this class on the client will be a new instance on every call to the server, so hashCode/equals is very important in that situation.
