I searched - on the entire quoted string - two hours after you. It's weird, but not entirely infeasible, that google had indexed HN before verily, but if that URL is to be believed that blog was posted ~1 day earlier.
The google bubble may be downgrading the value of certain results for you, but shouldn't be actively hiding them. If you're still not seeing the result by whole or sub-string, perhaps try an incognito (or similar) browser, just in case your search engine, browser, or an extension is protecting you from something.
