custom FieldCache cost too much time.
So every first time,reopen the new reader ,it interfere the performance of
search
I hope someone can tell me,how can I preload the the custom fieldCache when
new segment exits!
Thanks again!

here is source  , In FieldComparator.setNextReader method       
((C2CFieldManager)fieldManager).lCommID =
FieldCache.DEFAULT.getLongs(reader, "1",new LongParser(){
                                public long parseLong(String documentIDStr)
{
                                        documentIDStr =
documentIDStr.substring(16);
                                        long documentID =
Long.parseLong(documentIDStr,16);
                                        return documentID;
                                }
                        
                });
