Hi otis, Since i am maintaining more than 1.5 years records in the windows 2003 server,based on the user input for example if the user wants to display june 1 - june 15 folders and fetch the records from them.if the user wants to display may 1-may15 records i need to open those folders.thatswhy i am opening the index readers based on the user input.is it possible to create the array of index raders based on user input.
