dispatch.auto_pause = <int>
* If specified, the search job pauses after this many seconds of inactivity. (0
means never auto-pause.)
* To restart a paused search job, specify unpause as an action to POST
* auto_pause only goes into effect once. Unpausing after auto_pause does not
put auto_pause into effect again.
* Default is 0.
I'm not sure your exactly whether you want to do at user level or Role level. Hope it helps
