Error description

  • It has been identified that when a Quick Filter search is run
    against recent events, those searches can sometimes appear to
    be hung or stalled.
    In these particular instances, some of the QRadar indexer
    processes have been observed to be running behind (Lucene).
    Quick Filter searches run against recent events are waiting for
    the index of recent events to be completed prior to progressing.
