Scheduler
What Searchscope runs automatically, and when.
In appFoundationScheduler
What a run does
When it's on, the whole cycle runs on schedule: the search data comes in, the site is crawled, the analyzers run, and your briefing email goes out.
The page tells you when the next run is.
The five modules
Each controls one part of the run: the schedule, the data pull, the crawl, the analysis, and the briefing email. Work top to bottom; green means set.
Click any module to change its settings. When all five are set you can turn the runs on, and this is where you change them later.
Turning things off
The briefing can be switched off on its own, and automatic runs can be skipped altogether if you'd rather run things by hand.
