The most common reason searches get delayed are because of a lack of resources.

Check your CPU Usage in the Monitoring Console to get an idea of what may be causing it.

At a minimum your ES server should have 16 physical CPU cores or 32 Virtual CPU cores.

A temporary fix would be to switch your correlation searches to scheduled instead.
