If a tester entered a bug and you can't repro because the bug doesn't specify the environment, you'd rip 'em a new one. But someone uses two measly words to describe their test environment in this case, and now you question them about their eloquence?

Or maybe I have you wrong, so I'll ask: why would you ask why someone mentioned a specific search engine?

In case someone searched "UC Davis" and didn't find 3 articles in the results on Google or DuckDuckGo or some other search engine.

I didn't find that specification particularly odd, personally.

It wouldn't be weird if the specific search engine mentioned was Google.
