I read this question differently than other commenters. I think OP is asking if employees can use Google Search to search the internet like the rest of us, but they'd get decent results without the bloat. It would make sense as it would be in the company's best interest that the employees be shown meaningful results when they're trying to solve problems. A completely different index/ranking algorithm that punishes, instead of rewarding, all the fake SEO crap. Having said that, I have no idea.
