Dear All

I want to search result between to specific dates i am trying to use DateFilter its not working .where what i am doing

During Indexing i am getting date from DB in YYYY-MM-DD format.

Date rel_date=rs.getDate(6);

and using DateField to convert the date into String
and assign it to part of search index.

doc.add(Field.Keyword(DATE,DateField.dateToString(rel_date)));

During searh i am using following code
Date ldate=new Date(2001,11,11);
Date udate=new Date(2002,12,19);
DateFilter df=new DateFilter (IncreIndexTable.DATE,ldate,udate);
hits = searcher.search(query,df);


and its giving me nullpointer Exception .

any comments on it ?
if you have any other idea with code please describe it.

Thanx in advance
