How to pause/resume the crawler?


I’m using YaCy on my Computer and the Crawler IO slows it down considerably.
I’d need a method to pause/resume the crawler without stoping/restarting yacy alltogether so I can use my machine normally while I’m doing work or something else.

So lets say I want to pause crawling daytime and let it run at nighttime while being able to use yacy as a local search engine all day long.

Is there a way to pause/resume the crawler?
