Is There Any Way To Set Delay Between Searches On Per-Project Basis?

Hi Sven and everyone who is reading this.

I was wondering if there is a way to set a custom time delay between searches just for one project, if we want scraping behavior that would differ significantly from the Global Settings.

No, and there will be no option in the future either, because search engine delays are very critical and if just one project has exclusive control to it, it would mess up other projects as well. Such timing has to be managed globally.
