The default behavior of the Zebra system is to reference the
    records from their original location, i.e. where they were found when you
    run zebraidx.
    That is, when a client wishes to retrieve a record
    following a search operation, the files are accessed from the place
    where you originally put them - if you remove the files (without
    running zebraidx again, the server will return
    diagnostic number 14 (``System error in presenting records'') to
    the client.
   
    If your input files are not permanent - for example if you retrieve
    your records from an outside source, or if they were temporarily
    mounted on a CD-ROM drive,
    you may want Zebra to make an internal copy of them. To do this,
    you specify 1 (true) in the storeData setting. When
    the Z39.50 server retrieves the records they will be read from the
    internal file structures of the system.
