    Set shown in www_server log has no corresponding z05. [PRB 8291]

    We find that there is a "set_number=245655" reference in the www_server_log, but there is no z05 for this set. Why would that be?

    Sets are the result sets: the lists of document numbers which satisfy a particular query.
    After they are constructed they are stored as z05/z110 records in the vir01 library.

    If users go to "Previous Searches"/"History", they can ask to display a previous search they have done. The resulting URL command looks like this:.

    Some users may bookmark this URL and try to go to it several days later, by which time the set_number which it references has been cleared out of the z05.

    This does not cause any problem for the system; this simply means that users can't go back to previous searches after a certain period of time.
