To those who downvoted: is your position that Google's results are better in these two cases? Or that it doesn't matter? Or that the cost to match/exceed DDG's results outweighs the benefits? Or that since Google works differently behind the scenes it should not be expected to deliver these kinds of results?
Downvote? Really?
Likewise, it doesn't even make any sense to search for "college or college" without quotes. It makes even less sense when the internet includes an exact match on "college or uncollege". Oddly, a search for "college and uncollege" (without quotes) finds the article in the #1 position. Again, is it too much to ask that Google include a few exact match results even when it strongly suspects a miss-spelling?
